PTHREADS-WIN32 RELEASE 2.9.0 (2007-??-??)
-----------------------------------------
Web Site: http://sources.redhat.com/pthreads-win32/
FTP Site: ftp://sources.redhat.com/pub/pthreads-win32
Maintainer: Ross Johnson <rpj@callisto.canberra.edu.au>
We are pleased to announce the availability of a new release of
Pthreads-win32, an Open Source Software implementation of the
Threads component of the POSIX 1003.1 2001 Standard for Microsoft's
Win32 environment. Some functions from other sections of POSIX
1003.1 2001 are also supported including semaphores and scheduling
functions.
Some common non-portable functions are also implemented for
additional compatibility, as are a few functions specific
to pthreads-win32 for easier integration with Win32 applications.
Pthreads-win32 is free software, distributed under the GNU Lesser
General Public License (LGPL).
Acknowledgements
----------------
This library is based originally on a Win32 pthreads
implementation contributed by John Bossom <John.Bossom@cognos.com>.
The implementation of Condition Variables uses algorithms developed
by Alexander Terekhov and Louis Thomas.
The implementation of POSIX mutexes has been improved by Thomas Pfaff
and later by Alexander Terekhov.
The implementation of Spinlocks and Barriers was contributed
by Ross Johnson.
The implementation of read/write locks was contributed by
Aurelio Medina and improved by Alexander Terekhov.
Many others have contributed significant time and effort to solve crutial
problems in order to make the library workable, robust and reliable.
Thanks to Xavier Leroy for granting permission to use and modify his
LinuxThreads manual pages.
Thanks to The Open Group for making the Single Unix Specification
publicly available - many of the manual pages included in the package
were extracted from it.
There is also a separate CONTRIBUTORS file. This file and others are
on the web site:
http://sources.redhat.com/pthreads-win32
As much as possible, the ChangeLog file acknowledges contributions to the
code base in more detail.

Availability
------------
The prebuilt DLL, export libs (for both MSVC and Mingw32), and the header
files (pthread.h, semaphore.h, sched.h) are available along with the
complete source code.
The source code can be found at:
ftp://sources.redhat.com/pub/pthreads-win32
and as individual source code files at
ftp://sources.redhat.com/pub/pthreads-win32/source
The pre-built DLL, export libraries and include files can be found at:
ftp://sources.redhat.com/pub/pthreads-win32/dll-latest
Mailing List
------------
There is a mailing list for discussing pthreads on Win32. To join,
send email to:

Application Development Environments
------------------------------------
See the README file for more information.
MSVC:
MSVC using SEH works. Distribute pthreadVSE.dll with your application.
MSVC using C++ EH works. Distribute pthreadVCE.dll with your application.
MSVC using C setjmp/longjmp works. Distribute pthreadVC.dll with your application.
Mingw32:
See the FAQ, Questions 6 and 10.
Mingw using C++ EH works. Distribute pthreadGCE.dll with your application.
Mingw using C setjmp/longjmp works. Distribute pthreadGC.dll with your application.
Cygwin: (http://sourceware.cygnus.com/cygwin/)
Developers using Cygwin do not need pthreads-win32 since it has POSIX threads
support. Refer to its documentation for details and extent.
UWIN:
UWIN is a complete Unix-like environment for Windows from AT&T. Pthreads-win32
doesn't currently support UWIN (and vice versa), but that may change in the
future.
Generally:
For convenience, the following pre-built files are available on the FTP site
(see Availability above):
pthread.h - for POSIX threads
semaphore.h - for POSIX semaphores
sched.h - for POSIX scheduling
pthreadVCE.dll - built with MSVC++ compiler using C++ EH
pthreadVCE.lib
pthreadVC.dll - built with MSVC compiler using C setjmp/longjmp
pthreadVC.lib
pthreadVSE.dll - built with MSVC compiler using SEH
pthreadVSE.lib
pthreadGCE.dll - built with Mingw32 G++ 2.95.2-1
pthreadGC.dll - built with Mingw32 GCC 2.95.2-1 using setjmp/longjmp
libpthreadGCE.a - derived from pthreadGCE.dll
libpthreadGC.a - derived from pthreadGC.dll
gcc.dll - needed if distributing applications that use
pthreadGCE.dll (but see the FAQ Q 10 for the latest
related information)
These are the only files you need in order to build POSIX threads
applications for Win32 using either MSVC or Mingw32.
See the FAQ file in the source tree for additional information.
Documentation
-------------
For the authoritative reference, see the online POSIX
standard reference at:
http://www.OpenGroup.org
For POSIX Thread API programming, several reference books are
available:
Programming with POSIX Threads
David R. Butenhof
Addison-Wesley (pub)
Pthreads Programming
By Bradford Nichols, Dick Buttlar & Jacqueline Proulx Farrell
O'Reilly (pub)
On the web: see the links at the bottom of the pthreads-win32 site:
http://sources.redhat.com/pthreads-win32/
Currently, there is no documentation included in the package apart
from the copious comments in the source code.
Enjoy!

@ -1,141 +0,0 @@
----------
Known bugs
----------
1. Not strictly a bug, more of a gotcha.
Under MS VC++ (only tested with version 6.0), a term_func
set via the standard C++ set_terminate() function causes the
application to abort.
Notes from the MSVC++ manual:
1) A term_func() should call exit(), otherwise
abort() will be called on return to the caller.
A call to abort() raises SIGABRT and the default signal handler
for all signals terminates the calling program with
exit code 3.
2) A term_func() must not throw an exception. Therefore
term_func() should not call pthread_exit(), which
works by throwing an exception (pthreadVCE or pthreadVSE)
or by calling longjmp (pthreadVC).
Workaround: avoid using pthread_exit() in C++ applications. Exit
threads by dropping through the end of the thread routine.
2. Cancellation problems in C++ builds
- Milan Gardian
[Note: It's not clear if this problem isn't simply due to the context
switch in pthread_cancel() which occurs unless the QueueUserAPCEx
library and driver are installed and used. Just like setjmp/longjmp,
this is probably not going to work well in C++. In any case, unless for
some very unusual reason you really must use the C++ build then please
use the C build pthreadVC2.dll or pthreadGC2.dll, i.e. for C++
applications.]
This is suspected to be a compiler bug in VC6.0, and also seen in
VC7.0 and VS .NET 2003. The GNU C++ compiler does not have a problem
with this, and it has been reported that the Intel C++ 8.1 compiler
and Visual C++ 2005 Express Edition Beta2 pass tests\semaphore4.c
(which exposes the bug).
Workaround [rpj - 2 Feb 2002]
-----------------------------
[Please note: this workaround did not solve a similar problem in
snapshot-2004-11-03 or later, even though similar symptoms were seen.
tests\semaphore4.c fails in that snapshot for the VCE version of the
DLL.]
The problem disappears when /Ob0 is used, i.e. /O2 /Ob0 works OK,
but if you want to use inlining optimisation you can be much more
specific about where it's switched off and on by using a pragma.
So the inlining optimisation is interfering with the way that cleanup
handlers are run. It appears to relate to auto-inlining of class methods
since this is the only auto inlining that is performed at /O1 optimisation
(functions with the "inline" qualifier are also inlined, but the problem
doesn't appear to involve any such functions in the library or testsuite).
In order to confirm the inlining culprit, the following use of pragmas
eliminate the problem but I don't know how to make it transparent, putting
it in, say, pthread.h where pthread_cleanup_push defined as a macro.
#pragma inline_depth(0)
pthread_cleanup_push(handlerFunc, (void *) &arg);
/* ... */
pthread_cleanup_pop(0);
#pragma inline_depth()
Note the empty () pragma value after the pop macro. This resets depth to the
default. Or you can specify a non-zero depth here.
The pragma is also needed (and now used) within the library itself wherever
cleanup handlers are used (condvar.c and rwlock.c).
Use of these pragmas allows compiler optimisations /O1 and /O2 to be
used for either or both the library and applications.
Experimenting further, I found that wrapping the actual cleanup handler
function with #pragma auto_inline(off|on) does NOT work.
MSVC6.0 doesn't appear to support the C99 standard's _Pragma directive,
however, later versions may. This form is embeddable inside #define
macros, which would be ideal because it would mean that it could be added
to the push/pop macro definitions in pthread.h and hidden from the
application programmer.

Original problem description
----------------------------
The cancellation (actually, cleanup-after-cancel) tests fail when using VC
(professional) optimisation switches (/O1 or /O2) in pthreads library. I
have not investigated which concrete optimisation technique causes this
problem (/Og, /Oi, /Ot, /Oy, /Ob1, /Gs, /Gf, /Gy, etc.), but here is a
summary of builds and corresponding failures:
* pthreads VSE (optimised tests): OK
* pthreads VCE (optimised tests): Failed "cleanup1" test (runtime)
* pthreads VSE (DLL in CRT, optimised tests): OK
* pthreads VCE (DLL in CRT, optimised tests): Failed "cleanup1" test
(runtime)
Please note that while in VSE version of the pthreads library the
optimisation does not really have any impact on the tests (they pass OK), in
VCE version addition of optimisation (/O2 in this case) causes the tests to
fail uniformly - either in "cleanup0" or "cleanup1" test cases.
Please note that all the tests above use default pthreads DLL (no
optimisations, linked with either static or DLL CRT, based on test type).
Therefore the problem lies not within the pthreads DLL but within the
compiled client code (the application using pthreads -> involvement of
"pthread.h").
I think the message of this section is that usage of VCE version of pthreads
in applications relying on cancellation/cleanup AND using optimisations for
creation of production code is highly unreliable for the current version of
the pthreads library.
3. The Borland Builder 5.5 version of the library produces memory read exceptions
in some tests.
4. pthread_barrier_wait() can deadlock if the number of potential calling
threads for a particular barrier is greater than the barrier count parameter
given to pthread_barrier_init() for that barrier.
This is due to the very lightweight implementation of pthread-win32 barriers.
To cope with more than "count" possible waiters, barriers must effectively
implement all the same safeguards as condition variables, making them much
"heavier" than at present.
The workaround is to ensure that no more than "count" threads attempt to wait
at the barrier.
5. Canceling a thread blocked on pthread_once appears not to work in the MSVC++
version of the library "pthreadVCE.dll". The test case "once3.c" hangs. I have no
clues on this at present. All other versions pass this test ok - pthreadsVC.dll,
pthreadsVSE.dll, pthreadsGC.dll and pthreadsGCE.dll.

Why pthreads-win32 did not use the GNU General Public License
-------------------------------------------------------------
The goal of the pthreads-win32 project has been to
provide a quality and complete implementation of the POSIX
threads API for Microsoft Windows within the limits imposed
by virtue of it being a stand-alone library and not
linked directly to other POSIX compliant libraries. For
example, some functions and features, such as those based
on POSIX signals, are missing.
Pthreads-win32 is a library, available in several different
versions depending on supported compilers, and may be used
as a dynamically linked module or a statically linked set of
binary modules. It is not an application on it's own.
It was fully intended that pthreads-win32 be usable with
commercial software not covered by either the GPL or the LGPL
licenses. Pthreads-win32 has many contributors to it's
code base, many of whom have done so because they have
used the library in commercial or proprietry software
projects.
Releasing pthreads-win32 under the LGPL ensures that the
library can be used widely, while at the same time ensures
that bug fixes and improvements to the pthreads-win32 code
itself is returned to benefit all current and future users
of the library.
Although pthreads-win32 makes it possible for applications
that use POSIX threads to be ported to Win32 platforms, the
broader goal of the project is to encourage the use of open
standards, and in particular, to make it just a little easier
for developers writing Win32 applications to consider
widening the potential market for their products.

GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts
as the successor of the GNU Library Public License, version 2, hence
the version number 2.1.]
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
Licenses are intended to guarantee your freedom to share and change
free software--to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some
specially designated software packages--typically libraries--of the
Free Software Foundation and other authors who decide to use it. You
can use it too, but we suggest you first think carefully about whether
this license or the ordinary General Public License is the better
strategy to use in any particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use,
not price. Our General Public Licenses are designed to make sure that
you have the freedom to distribute copies of free software (and charge
for this service if you wish); that you receive source code or can get
it if you want it; that you can change the software and use pieces of
it in new free programs; and that you are informed that you can do
these things.
To protect your rights, we need to make restrictions that forbid
distributors to deny you these rights or to ask you to surrender these
rights. These restrictions translate to certain responsibilities for
you if you distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis
or for a fee, you must give the recipients all the rights that we gave
you. You must make sure that they, too, receive or can get the source
code. If you link other code with the library, you must provide
complete object files to the recipients, so that they can relink them
with the library after making changes to the library and recompiling
it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal
permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that
there is no warranty for the free library. Also, if the library is
modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original
author's reputation will not be affected by problems that might be
introduced by others.
Finally, software patents pose a constant threat to the existence of
any free program. We wish to make sure that a company cannot
effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder. Therefore, we insist that
any patent license obtained for a version of the library must be
consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the
ordinary GNU General Public License. This license, the GNU Lesser
General Public License, applies to certain designated libraries, and
is quite different from the ordinary General Public License. We use
this license for certain libraries in order to permit linking those
libraries into non-free programs.
When a program is linked with a library, whether statically or using
a shared library, the combination of the two is legally speaking a
combined work, a derivative of the original library. The ordinary
General Public License therefore permits such linking only if the
entire combination fits its criteria of freedom. The Lesser General
Public License permits more lax criteria for linking other code with
the library.
We call this license the "Lesser" General Public License because it
does Less to protect the user's freedom than the ordinary General
Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages
are the reason we use the ordinary General Public License for many
libraries. However, the Lesser license provides advantages in certain
special circumstances.
For example, on rare occasions, there may be a special need to
encourage the widest possible use of a certain library, so that it becomes
a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free
library does the same job as widely used non-free libraries. In this
case, there is little to gain by limiting the free library to free
software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free
programs enables a greater number of people to use a large body of
free software. For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU
operating system, as well as its variant, the GNU/Linux operating
system.
Although the Lesser General Public License is Less protective of the
users' freedom, it does ensure that the user of a program that is
linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a
"work based on the library" and a "work that uses the library". The
former contains code derived from the library, whereas the latter must
be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other
program which contains a notice placed by the copyright holder or
other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License").
Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work
which has been distributed under these terms. A "work based on the
Library" means either the Library or any derivative work under
copyright law: that is to say, a work containing the Library or a
portion of it, either verbatim or with modifications and/or translated
straightforwardly into another language. (Hereinafter, translation is
included without limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for
making modifications to it. For a library, complete source code means
all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation
and installation of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running a program using the Library is not restricted, and output from
such a program is covered only if its contents constitute a work based
on the Library (independent of the use of the Library in a tool for
writing it). Whether that is true depends on what the Library does
and what the program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's
complete source code as you receive it, in any medium, provided that
you conspicuously and appropriately publish on each copy an
appropriate copyright notice and disclaimer of warranty; keep intact
all the notices that refer to this License and to the absence of any
warranty; and distribute a copy of this License along with the
Library.
You may charge a fee for the physical act of transferring a copy,
and you may at your option offer warranty protection in exchange for a
fee.
2. You may modify your copy or copies of the Library or any portion
of it, thus forming a work based on the Library, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no
charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a
table of data to be supplied by an application program that uses
the facility, other than as an argument passed when the facility
is invoked, then you must make a good faith effort to ensure that,
in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of
its purpose remains meaningful.
(For example, a function in a library to compute square roots has
a purpose that is entirely well-defined independent of the
application. Therefore, Subsection 2d requires that any
application-supplied function or table used by this function must
be optional: if the application does not supply it, the square
root function must still compute square roots.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Library,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Library, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote
it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do
this, you must alter all the notices that refer to this License, so
that they refer to the ordinary GNU General Public License, version 2,
instead of to this License. (If a newer version than version 2 of the
ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is irreversible for
that copy, so the ordinary GNU General Public License applies to all
subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of
the Library into a program that is not a library.
4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable form
under the terms of Sections 1 and 2 above provided that you accompany
it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made by offering access to copy
from a designated place, then offering equivalent access to copy the
source code from the same place satisfies the requirement to
distribute the source code, even though third parties are not
compelled to copy the source along with the object code.
5. A program that contains no derivative of any portion of the
Library, but is designed to work with the Library by being compiled or
linked with it, is called a "work that uses the Library". Such a
work, in isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library
creates an executable that is a derivative of the Library (because it
contains portions of the Library), rather than a "work that uses the
library". The executable is therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file
that is part of the Library, the object code for the work may be a
derivative work of the Library even though the source code is not.
Whether this is true is especially significant if the work can be
linked without the Library, or if the work is itself a library. The
threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline
functions (ten lines or less in length), then the use of the object
file is unrestricted, regardless of whether it is legally a derivative
work. (Executables containing this object code plus portions of the
Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may
distribute the object code for the work under the terms of Section 6.
Any executables containing that work also fall under Section 6,
whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or
link a "work that uses the Library" with the Library to produce a
work containing portions of the Library, and distribute that work
under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse
engineering for debugging such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked
with the Library, with the complete machine-readable "work that
uses the Library", as object code and/or source code, so that the
user can modify the Library and then relink to produce a modified
executable containing the modified Library. (It is understood
that the user who changes the contents of definitions files in the
Library will not necessarily be able to recompile the application
to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the
Library. A suitable mechanism is one that (1) uses at run time a
copy of the library already present on the user's computer system,
rather than copying library functions into the executable, and (2)
will operate properly with a modified version of the library, if
the user installs one, as long as the modified version is
interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy
from a designated place, offer equivalent access to copy the above
specified materials from the same place.
e) Verify that the user has already received a copy of these
materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the
Library" must include any data and utility programs needed for
reproducing the executable from it. However, as a special exception,
the materials to be distributed need not include anything that is
normally distributed (in either source or binary form) with the major
components (compiler, kernel, and so on) of the operating system on
which the executable runs, unless that component itself accompanies
the executable.
It may happen that this requirement contradicts the license
restrictions of other proprietary libraries that do not normally
accompany the operating system. Such a contradiction means you cannot
use both them and the Library together in an executable that you
distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other library
facilities not covered by this License, and distribute such a combined
library, provided that the separate distribution of the work based on
the Library and of the other library facilities is otherwise
permitted, and provided that you do these two things:
a) Accompany the combined library with a copy of the same work
based on the Library, uncombined with any other library
facilities. This must be distributed under the terms of the
Sections above.
b) Give prominent notice with the combined library of the fact
that part of it is a work based on the Library, and explaining
where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License. Any
attempt otherwise to copy, modify, sublicense, link with, or
distribute the Library is void, and will automatically terminate your
rights under this License. However, parties who have received copies,
or rights, from you under this License will not have their licenses
terminated so long as such parties remain in full compliance.
9. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Library (or any work based on the
Library), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the
original licensor to copy, distribute, link with or modify the Library
subject to these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties with
this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Library at all. For example, if a patent
license would not permit royalty-free redistribution of the Library by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply,
and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries,
so that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time.
Such new versions will be similar in spirit to the present version,
but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and
"any later version", you have the option of following the terms and
conditions either of that version or of any later version published by
the Free Software Foundation. If the Library does not specify a
license version number, you may choose any version ever published by
the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free
programs whose distribution conditions are incompatible with these,
write to the author to ask for permission. For software which is
copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our
decision will be guided by the two goals of preserving the free status
of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest
possible use to the public, we recommend making it free software that
everyone can redistribute and change. You can do so by permitting
redistribution under these terms (or, alternatively, under the terms of the
ordinary General Public License).
To apply these terms, attach the following notices to the library. It is
safest to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.
<one line to give the library's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>

modify it under the terms of the GNU Lesser General Public
License as published by the Free Software Foundation; either
version 2.1 of the License, or (at your option) any later version.
This library is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of

License along with this library; if not, write to the Free Software

Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if
necessary. Here is a sample; alter the names:

=============================================================================
Q 1 What is it?
---
Pthreads-win32 is an Open Source Software implementation of the
Threads component of the POSIX 1003.1c 1995 Standard for Microsoft's
Win32 environment. Some functions from POSIX 1003.1b are also
supported including semaphores. Other related functions include
the set of read-write lock functions. The library also supports
some of the functionality of the Open Group's Single Unix
specification, version 2, namely mutex types.
See the file "ANNOUNCE" for more information including standards
conformance details and list of supported routines.
------------------------------------------------------------------------------
Q 2 Which of the several dll versions do I use?
--- or,
What are all these pthread*.dll and pthread*.lib files?
Simply, you only use one of them, but you need to choose carefully.
The most important choice you need to make is whether to use a
version that uses exceptions internally, or not (there are versions
of the library that use exceptions as part of the thread
cancelation and cleanup implementation, and one that uses
setjmp/longjmp instead).
There is some contension amongst POSIX threads experts as
to how POSIX threads cancelation and exit should work
with languages that include exceptions and handlers, e.g.
C++ and even C (Microsoft's Structured Exceptions).
The issue is: should cancelation of a thread in, say,
a C++ application cause object destructors and C++ exception
handlers to be invoked as the stack unwinds during thread
exit, or not?
There seems to be more opinion in favour of using the
standard C version of the library (no EH) with C++ applications
since this appears to be the assumption commercial pthreads
implementations make. Therefore, if you use an EH version
of pthreads-win32 then you may be under the illusion that
your application will be portable, when in fact it is likely to
behave very differently linked with other pthreads libraries.
Now you may be asking: why have you kept the EH versions of
the library?
There are a couple of reasons:
- there is division amongst the experts and so the code may
be needed in the future. (Yes, it's in the repository and we
can get it out anytime in the future, but ...)
- pthreads-win32 is one of the few implementations, and possibly
the only freely available one, that has EH versions. It may be
useful to people who want to play with or study application
behaviour under these conditions.
------------------------------------------------------------------------------
Q 3 What is the library naming convention?
---
Because the library is being built using various exception
handling schemes and compilers - and because the library
may not work reliably if these are mixed in an application,
each different version of the library has it's own name.
Note 1: the incompatibility is really between EH implementations
of the different compilers. It should be possible to use the
standard C version from either compiler with C++ applications
built with a different compiler. If you use an EH version of
the library, then you must use the same compiler for the
application. This is another complication and dependency that
can be avoided by using only the standard C library version.
Note 2: if you use a standard C pthread*.dll with a C++
application, then any functions that you define that are
intended to be called via pthread_cleanup_push() must be
__cdecl.
Note 3: the intention is to also name either the VC or GC
version (it should be arbitrary) as pthread.dll, including
pthread.lib and libpthread.a as appropriate.
In general:
pthread[VG]{SE,CE,C}.dll
pthread[VG]{SE,CE,C}.lib
where:
[VG] indicates the compiler
V - MS VC
G - GNU C
{SE,CE,C} indicates the exception handling scheme
SE - Structured EH
CE - C++ EH
C - no exceptions - uses setjmp/longjmp
For example:
pthreadVSE.dll (MSVC/SEH)
pthreadGCE.dll (GNUC/C++ EH)
pthreadGC.dll (GNUC/not dependent on exceptions)
The GNU library archive file names have changed to:
libpthreadGCE.a
libpthreadGC.a
------------------------------------------------------------------------------
Q 4 Cleanup code default style or: it used to work when I built
--- the library myself, but now it doesn't - why?
Up to and including snapshot 2001-07-12, if not defined, the cleanup
style was determined automatically from the compiler used, and one
of the following was defined accordingly:
__CLEANUP_SEH MSVC only
__CLEANUP_CXX C++, including MSVC++, GNU G++
__CLEANUP_C C, including GNU GCC, not MSVC
These defines determine the style of cleanup (see pthread.h) and,
most importantly, the way that cancelation and thread exit (via
pthread_exit) is performed (see the routine ptw32_throw() in private.c).
In short, the exceptions versions of the library throw an exception
when a thread is canceled or exits (via pthread_exit()), which is
caught by a handler in the thread startup routine, so that the
the correct stack unwinding occurs regardless of where the thread
is when it's canceled or exits via pthread_exit().
After snapshot 2001-07-12, unless your build explicitly defines (e.g.
via a compiler option) __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then
the build now ALWAYS defaults to __CLEANUP_C style cleanup. This style
uses setjmp/longjmp in the cancelation and pthread_exit implementations,
and therefore won't do stack unwinding even when linked to applications
that have it (e.g. C++ apps). This is for consistency with most/all
commercial Unix POSIX threads implementations.
Although it was not clearly documented before, it is still necessary to
build your application using the same __CLEANUP_* define as was
used for the version of the library that you link with, so that the
correct parts of pthread.h are included. That is, the possible
defines require the following library versions:
__CLEANUP_SEH pthreadVSE.dll
__CLEANUP_CXX pthreadVCE.dll or pthreadGCE.dll
__CLEANUP_C pthreadVC.dll or pthreadGC.dll
THE POINT OF ALL THIS IS: if you have not been defining one of these
explicitly, then the defaults have been set according to the compiler
and language you are using, as described at the top of this
section.
THIS NOW CHANGES, as has been explained above. For example:
If you were building your application with MSVC++ i.e. using C++
exceptions (rather than SEH) and not explicitly defining one of
__CLEANUP_*, then __CLEANUP_C++ was defined for you in pthread.h.
You should have been linking with pthreadVCE.dll, which does
stack unwinding.
If you now build your application as you had before, pthread.h will now
set __CLEANUP_C as the default style, and you will need to link
with pthreadVC.dll. Stack unwinding will now NOT occur when a
thread is canceled, nor when the thread calls pthread_exit().
Your application will now most likely behave differently to previous
versions, and in non-obvious ways. Most likely is that local
objects may not be destroyed or cleaned up after a thread
is canceled.
If you want the same behaviour as before, then you must now define
__CLEANUP_C++ explicitly using a compiler option and link with
pthreadVCE.dll as you did before.
------------------------------------------------------------------------------
Q 5 Why is the default library version now less exception-friendly?
---
Because most commercial Unix POSIX threads implementations don't allow you to
choose to have stack unwinding. (Compaq's TRU64 Unix is possibly an exception.)
Therefore, providing it in pthread-win32 as a default could be dangerous
and non-portable. We still provide the choice but you must now consciously
make it.
WHY NOT REMOVE THE EXCEPTIONS VERSIONS OF THE LIBRARY ALTOGETHER?
There are a few reasons:
- because there are well respected POSIX threads people who believe
that POSIX threads implementations should be exceptions-aware and
do the expected thing in that context. (There are equally respected
people who believe it should not be easily accessible, if it's there
at all.)
- because pthreads-win32 is one of the few implementations that has
the choice, perhaps the only freely available one, and so offers
a laboratory to people who may want to explore the effects;
- although the code will always be around somewhere for anyone who
wants it, once it's removed from the current version it will not be
nearly as visible to people who may have a use for it.
------------------------------------------------------------------------------
Q 6 Should I use Cygwin or Mingw32 as a development environment?
---
Important: see Q7 also.
Use Mingw32 with the MSVCRT library to build applications that use
the pthreads DLL.
Cygwin's own internal support for POSIX threads is growing.
Consult that project's documentation for more information.
------------------------------------------------------------------------------
Q 7 Now that pthreads-win32 builds under Mingw32, why do I get
--- memory access violations (segfaults)?
The latest Mingw32 package has thread-safe exception handling (see Q10).
Also, see Q6 above.
------------------------------------------------------------------------------

You should have a .dll, .lib, .def, and three .h files. It is recommended
that you use pthreadVC.dll, rather than pthreadVCE.dll or pthreadVSE.dll
(see Q2 above).
The .dll can go in any directory listed in your PATH environment
variable, so putting it into C:\WINDOWS should work.
The .lib file can go in any directory listed in your LIB environment
variable.
The .h files can go in any directory listed in your INCLUDE
environment variable.
Or you might prefer to put the .lib and .h files into a new directory
and add its path to LIB and INCLUDE. You can probably do this easiest
by editing the file:-
C:\Program Files\DevStudio\vc\bin\vcvars32.bat
The .def file isn't used by anything in the pre-compiled version but
is included for information.
Cheers.

The answer to your first question is, normal POSIX behaviour would
be to asynchronously cancel the thread. However, even that doesn't
guarantee cancelation as the standard only says it should be
cancelled as soon as possible.
Snapshot 99-11-02 or earlier only partially supports asynchronous cancellation.
Snapshots since then simulate async cancelation by poking the address of
a cancelation routine into the PC of the threads context. This requires
the thread to be resumed in some way for the cancelation to actually
proceed. This is not true async cancelation, but it is as close as we've
been able to get to it.
If the thread you're trying to cancel is blocked (for instance, it could be
waiting for data from the network), it will only get cancelled when it unblocks
(when the data arrives). For true pre-emptive cancelation in these cases,
pthreads-win32 from snapshot 2004-05-16 can automatically recognise and use the
QueueUserAPCEx package by Panagiotis E. Hadjidoukas. This package is available
from the pthreads-win32 ftp site and is included in the pthreads-win32
self-unpacking zip from 2004-05-16 onwards.
Using deferred cancelation would normally be the way to go, however,
even though the POSIX threads standard lists a number of C library
functions that are defined as deferred cancelation points, there is
no hookup between those which are provided by Windows and the
pthreads-win32 library.
Incidently, it's worth noting for code portability that the older POSIX
threads standards cancelation point lists didn't include "select" because
(as I read in Butenhof) it wasn't part of POSIX. However, it does appear in
the SUSV3.
Effectively, the only mandatory cancelation points that pthreads-win32
recognises are those the library implements itself, ie.
pthread_testcancel
pthread_cond_wait
pthread_cond_timedwait
pthread_join
sem_wait
sem_timedwait
pthread_delay_np
The following routines from the non-mandatory list in SUSV3 are
cancelation points in pthreads-win32:
pthread_rwlock_wrlock
pthread_rwlock_timedwrlock
The following routines from the non-mandatory list in SUSV3 are not
cancelation points in pthreads-win32:
pthread_rwlock_rdlock
pthread_rwlock_timedrdlock
Pthreads-win32 also provides two functions that allow you to create
cancelation points within your application, but only for cases where
a thread is going to block on a Win32 handle. These are:
pthreadCancelableWait(HANDLE waitHandle) /* Infinite wait */
pthreadCancelableTimedWait(HANDLE waitHandle, DWORD timeout)

Q 10 How do I create thread-safe applications using
---- pthreadGCE.dll, libpthreadw32.a and Mingw32?
This should not be a problem with recent versions of MinGW32.
For early versions, see Thomas Pfaff's email at:
http://sources.redhat.com/ml/pthreads-win32/2002/msg00000.html
------------------------------------------------------------------------------
Q 11 Why isn't pthread_t defined as a scalar (e.g. pointer or int)
like it is for other POSIX threads implementations?
----
Originally pthread_t was defined as a pointer (to the opaque pthread_t_
struct) and later it was changed to a struct containing the original
pointer plus a sequence counter. This is allowed under both the original
POSIX Threads Standard and the current Single Unix Specification.
When pthread_t is a simple pointer to a struct some very difficult to
debug problems arise from the process of freeing and later allocing
thread structs because new pthread_t handles can acquire the identity of
previously detached threads. The change to a struct was made, along with
some changes to their internal managment, in order to guarantee (for
practical applications) that the pthread_t handle will be unique over the
life of the running process.
Where application code attempts to compare one pthread_t against another
directly, a compiler error will be emitted because structs can't be
compared at that level. This should signal a potentially serious problem
in the code design, which would go undetected if pthread_t was a scalar.
The POSIX Threading API provides a function named pthread_equal() to
compare pthread_t thread handles.
Other pthreads implementations, such as Sun's, use an int as the handle
but do guarantee uniqueness within the process scope. Win32 scalar typed
thread handles also guarantee uniqueness in system scope. It wasn't clear
how well the internal management of these handles would scale as the
number of threads and the fragmentation of the sequence numbering
increased for applications where thousands or millions of threads are
created and detached over time. The current management of threads within
pthreads-win32 using structs for pthread_t, and reusing without ever
freeing them, reduces the management time overheads to a constant, which
could be important given that pthreads-win32 threads are built on top of
Win32 threads and will therefore include that management overhead on top
of their own. The cost is that the memory resources used for thread
handles will remain at the peak level until the process exits.
While it may be inconvenient for developers to be forced away from making
assumptions about the internals of pthread_t, the advantage for the
future development of pthread-win32, as well as those applications that
use it and other pthread implementations, is that the library is free to
change pthread_t internals and management as better methods arise.

# The library can be built with some alternative behaviour to
# facilitate development of applications on Win32 that will be ported
# to other POSIX systems. Nothing definable here will make the library
# non-compliant, but applications that make assumptions that POSIX
# does not garrantee may fail or misbehave under some settings.
#
# PTW32_THREAD_ID_REUSE_INCREMENT
# Purpose:
# POSIX says that applications should assume that thread IDs can be
# recycled. However, Solaris and some other systems use a [very large]
# sequence number as the thread ID, which provides virtual uniqueness.
# Pthreads-win32 provides pseudo-unique IDs when the default increment
# (1) is used, but pthread_t is not a scalar type like Solaris's.
#
# Usage:
# Set to any value in the range: 0 <= value <= 2^wordsize
#
# Examples:
# Set to 0 to emulate non recycle-unique behaviour like Linux or *BSD.
# Set to 1 for recycle-unique thread IDs (this is the default).
# Set to some other +ve value to emulate smaller word size types
# (i.e. will wrap sooner).

#PTW32_FLAGS = "-DPTW32_THREAD_ID_REUSE_INCREMENT=0"

PTHREADS-WIN32
==============
Pthreads-win32 is free software, distributed under the GNU Lesser
General Public License (LGPL). See the file 'COPYING.LIB' for terms
and conditions. Also see the file 'COPYING' for information
specific to pthreads-win32, copyrights and the LGPL.
What is it?
-----------
Pthreads-win32 is an Open Source Software implementation of the
Threads component of the POSIX 1003.1c 1995 Standard (or later)
for Microsoft's Win32 environment. Some functions from POSIX
1003.1b are also supported including semaphores. Other related
functions include the set of read-write lock functions. The
library also supports some of the functionality of the Open
Group's Single Unix specification, version 2, namely mutex types,
plus some common and pthreads-win32 specific non-portable
routines (see README.NONPORTABLE).
See the file "ANNOUNCE" for more information including standards
conformance details and the list of supported and unsupported
routines.
Prerequisites
-------------
MSVC or GNU C (MinGW32 MSys development kit)
To build from source.
QueueUserAPCEx by Panagiotis E. Hadjidoukas
To support any thread cancelation in C++ library builds or
to support cancelation of blocked threads in any build.
This library is not required otherwise.
For true async cancelation of threads (including blocked threads).
This is a DLL and Windows driver that provides pre-emptive APC
by forcing threads into an alertable state when the APC is queued.
Both the DLL and driver are provided with the pthreads-win32.exe
self-unpacking ZIP, and on the pthreads-win32 FTP site (in source
and pre-built forms). Currently this is a separate LGPL package to
pthreads-win32. See the README in the QueueUserAPCEx folder for
installation instructions.
Pthreads-win32 will automatically detect if the QueueUserAPCEx DLL
QuserEx.DLL is available and whether the driver AlertDrv.sys is
loaded. If it is not available, pthreads-win32 will simulate async
cancelation, which means that it can async cancel only threads that
are runnable. The simulated async cancellation cannot cancel blocked
threads.
[FOR SECURITY] To be found Quserex.dll MUST be installed in the
Windows System Folder. This is not an unreasonable constraint given a
driver must also be installed and loaded at system startup.
Library naming
--------------
Because the library is being built using various exception
handling schemes and compilers - and because the library
may not work reliably if these are mixed in an application,
each different version of the library has it's own name.
Note 1: the incompatibility is really between EH implementations
of the different compilers. It should be possible to use the
standard C version from either compiler with C++ applications
built with a different compiler. If you use an EH version of
the library, then you must use the same compiler for the
application. This is another complication and dependency that
can be avoided by using only the standard C library version.
Note 2: if you use a standard C pthread*.dll with a C++
application, then any functions that you define that are
intended to be called via pthread_cleanup_push() must be
__cdecl.
Note 3: the intention was to also name either the VC or GC
version (it should be arbitrary) as pthread.dll, including
pthread.lib and libpthread.a as appropriate. This is no longer
likely to happen.
Note 4: the compatibility number was added so that applications
can differentiate between binary incompatible versions of the
libs and dlls.
In general:
pthread[VG]{SE,CE,C}[c].dll
pthread[VG]{SE,CE,C}[c].lib
where:
[VG] indicates the compiler
V - MS VC, or
G - GNU C
{SE,CE,C} indicates the exception handling scheme
SE - Structured EH, or
CE - C++ EH, or
C - no exceptions - uses setjmp/longjmp
c - DLL compatibility number indicating ABI and API
compatibility with applications built against
a snapshot with the same compatibility number.
See 'Version numbering' below.
The name may also be suffixed by a 'd' to indicate a debugging version
of the library. E.g. pthreadVC2d.lib. Debugging versions contain
additional information for debugging (symbols etc) and are often not
optimised in any way (compiled with optimisation turned off).
Examples:
pthreadVSE.dll (MSVC/SEH)
pthreadGCE.dll (GNUC/C++ EH)
pthreadGC.dll (GNUC/not dependent on exceptions)
pthreadVC1.dll (MSVC/not dependent on exceptions - not binary
compatible with pthreadVC.dll)
pthreadVC2.dll (MSVC/not dependent on exceptions - not binary
compatible with pthreadVC1.dll or pthreadVC.dll)
The GNU library archive file names have correspondingly changed to:
libpthreadGCEc.a
libpthreadGCc.a
Versioning numbering
--------------------
Version numbering is separate from the snapshot dating system, and
is the canonical version identification system embedded within the
DLL using the Microsoft version resource system. The versioning
system chosen follows the GNU Libtool system. See
http://www.gnu.org/software/libtool/manual.html section 6.2.
See the resource file 'version.rc'.
Microsoft version numbers use 4 integers:
0.0.0.0
Pthreads-win32 uses the first 3 following the Libtool convention.
The fourth is commonly used for the build number, but will be reserved
for future use.
current.revision.age.0
The numbers are changed as follows:
1. If the library source code has changed at all since the last update,
then increment revision (`c:r:a' becomes `c:r+1:a').
2. If any interfaces have been added, removed, or changed since the last
update, increment current, and set revision to 0.
3. If any interfaces have been added since the last public release, then
increment age.
4. If any interfaces have been removed or changed since the last public
release, then set age to 0.
DLL compatibility numbering is an attempt to ensure that applications
always load a compatible pthreads-win32 DLL by using a DLL naming system
that is consistent with the version numbering system. It also allows
older and newer DLLs to coexist in the same filesystem so that older
applications can continue to be used. For pre .NET Windows systems,
this inevitably requires incompatible versions of the same DLLs to have
different names.
Pthreads-win32 has adopted the Cygwin convention of appending a single
integer number to the DLL name. The number used is based on the library
version number and is computed as 'current' - 'age'.
(See http://home.att.net/~perlspinr/libversioning.html for a nicely
detailed explanation.)
Using this method, DLL name/s will only change when the DLL's
backwards compatibility changes. Note that the addition of new
'interfaces' will not of itself change the DLL's compatibility for older
applications.
Which of the several dll versions to use?
-----------------------------------------
or,
---
What are all these pthread*.dll and pthread*.lib files?
-------------------------------------------------------
Simple, use either pthreadGCv.* if you use GCC, or pthreadVCv.* if you
use MSVC - where 'v' is the DLL versioning (compatibility) number.
Otherwise, you need to choose carefully and know WHY.
The most important choice you need to make is whether to use a
version that uses exceptions internally, or not. There are versions
of the library that use exceptions as part of the thread
cancelation and exit implementation. The default version uses
setjmp/longjmp.
There is some contension amongst POSIX threads experts as
to how POSIX threads cancelation and exit should work
with languages that use exceptions, e.g. C++ and even C
(Microsoft's Structured Exceptions).
The issue is: should cancelation of a thread in, say,
a C++ application cause object destructors and C++ exception
handlers to be invoked as the stack unwinds during thread
exit, or not?
There seems to be more opinion in favour of using the
standard C version of the library (no EH) with C++ applications
for the reason that this appears to be the assumption commercial
pthreads implementations make. Therefore, if you use an EH version
of pthreads-win32 then you may be under the illusion that
your application will be portable, when in fact it is likely to
behave differently when linked with other pthreads libraries.
Now you may be asking: then why have you kept the EH versions of
the library?
There are a couple of reasons:
- there is division amongst the experts and so the code may
be needed in the future. Yes, it's in the repository and we
can get it out anytime in the future, but it would be difficult
to find.
- pthreads-win32 is one of the few implementations, and possibly
the only freely available one, that has EH versions. It may be
useful to people who want to play with or study application
behaviour under these conditions.
Notes:
[If you use either pthreadVCE or pthreadGCE]
1. [See also the discussion in the FAQ file - Q2, Q4, and Q5]
If your application contains catch(...) blocks in your POSIX
threads then you will need to replace the "catch(...)" with the macro
"PtW32Catch", eg.
#ifdef PtW32Catch
PtW32Catch {
...
}
#else
catch(...) {
...
}
#endif
Otherwise neither pthreads cancelation nor pthread_exit() will work
reliably when using versions of the library that use C++ exceptions
for cancelation and thread exit.
This is due to what is believed to be a C++ compliance error in VC++
whereby you may not have multiple handlers for the same exception in
the same try/catch block. GNU G++ doesn't have this restriction.
Other name changes
------------------
All snapshots prior to and including snapshot 2000-08-13
used "_pthread_" as the prefix to library internal
functions, and "_PTHREAD_" to many library internal
macros. These have now been changed to "ptw32_" and "PTW32_"
respectively so as to not conflict with the ANSI standard's
reservation of identifiers beginning with "_" and "__" for
use by compiler implementations only.
If you have written any applications and you are linking
statically with the pthreads-win32 library then you may have
included a call to _pthread_processInitialize. You will
now have to change that to ptw32_processInitialize.
Cleanup code default style
--------------------------
Previously, if not defined, the cleanup style was determined automatically
from the compiler used, and one of the following was defined accordingly:
__CLEANUP_SEH MSVC only
__CLEANUP_CXX C++, including MSVC++, GNU G++
__CLEANUP_C C, including GNU GCC, not MSVC
These defines determine the style of cleanup (see pthread.h) and,
most importantly, the way that cancelation and thread exit (via
pthread_exit) is performed (see the routine ptw32_throw()).
In short, the exceptions versions of the library throw an exception
when a thread is canceled, or exits via pthread_exit(). This exception is
caught by a handler in the thread startup routine, so that the
the correct stack unwinding occurs regardless of where the thread
is when it's canceled or exits via pthread_exit().
In this snapshot, unless the build explicitly defines (e.g. via a
compiler option) __CLEANUP_SEH, __CLEANUP_CXX, or __CLEANUP_C, then
the build NOW always defaults to __CLEANUP_C style cleanup. This style
uses setjmp/longjmp in the cancelation and pthread_exit implementations,
and therefore won't do stack unwinding even when linked to applications
that have it (e.g. C++ apps). This is for consistency with most/all
commercial Unix POSIX threads implementations.
Although it was not clearly documented before, it is still necessary to
build your application using the same __CLEANUP_* define as was
used for the version of the library that you link with, so that the
correct parts of pthread.h are included. That is, the possible
defines require the following library versions:
__CLEANUP_SEH pthreadVSE.dll
__CLEANUP_CXX pthreadVCE.dll or pthreadGCE.dll
__CLEANUP_C pthreadVC.dll or pthreadGC.dll
It is recommended that you let pthread.h use it's default __CLEANUP_C
for both library and application builds. That is, don't define any of
the above, and then link with pthreadVC.lib (MSVC or MSVC++) and
libpthreadGC.a (MinGW GCC or G++). The reason is explained below, but
another reason is that the prebuilt pthreadVCE.dll is currently broken.
Versions built with MSVC++ later than version 6 may not be broken, but I
can't verify this yet.
WHY ARE WE MAKING THE DEFAULT STYLE LESS EXCEPTION-FRIENDLY?
Because no commercial Unix POSIX threads implementation allows you to
choose to have stack unwinding. Therefore, providing it in pthread-win32
as a default is dangerous. We still provide the choice but unless
you consciously choose to do otherwise, your pthreads applications will
now run or crash in similar ways irrespective of the pthreads platform
you use. Or at least this is the hope.
Building under VC++ using C++ EH, Structured EH, or just C
----------------------------------------------------------
From the source directory run nmake without any arguments to list
help information. E.g.
$ nmake
Microsoft (R) Program Maintenance Utility Version 6.00.8168.0
Copyright (C) Microsoft Corp 1988-1998. All rights reserved.
Run one of the following command lines:
nmake clean VCE (to build the MSVC dll with C++ exception handling)
nmake clean VSE (to build the MSVC dll with structured exception handling)
nmake clean VC (to build the MSVC dll with C cleanup code)
nmake clean VCE-inlined (to build the MSVC inlined dll with C++ exception handling)
nmake clean VSE-inlined (to build the MSVC inlined dll with structured exception handling)
nmake clean VC-inlined (to build the MSVC inlined dll with C cleanup code)

nmake clean VC-static-debug (to build the debug MSVC static lib with C cleanup code)
The pre-built dlls are normally built using the *-inlined targets.
You can run the testsuite by changing to the "tests" directory and
running nmake. E.g.:
$ cd tests
$ nmake

Run one of the following command lines:
nmake clean VC (to test using VC dll with VC (no EH) applications)
nmake clean VCX (to test using VC dll with VC++ (EH) applications)
nmake clean VCE (to test using the VCE dll with VC++ EH applications)
nmake clean VSE (to test using VSE dll with VC (SEH) applications)
nmake clean VC-bench (to benchtest using VC dll with C bench app)
nmake clean VCX-bench (to benchtest using VC dll with C++ bench app)
nmake clean VCE-bench (to benchtest using VCE dll with C++ bench app)
nmake clean VSE-bench (to benchtest using VSE dll with SEH bench app)
nmake clean VC-static (to test using VC static lib with VC (no EH) applications)
Building under Mingw32
----------------------
The dll can be built easily with recent versions of Mingw32.
(The distributed versions are built using Mingw32 and MsysDTK
from www.mingw32.org.)
From the source directory, run make for help information. E.g.:
$ make
Run one of the following command lines:
make clean GC (to build the GNU C dll with C cleanup code)
make clean GCE (to build the GNU C dll with C++ exception handling)
make clean GC-inlined (to build the GNU C inlined dll with C cleanup code)
make clean GCE-inlined (to build the GNU C inlined dll with C++ exception handling)
make clean GC-static (to build the GNU C inlined static lib with C cleanup code)
make clean GC-debug (to build the GNU C debug dll with C cleanup code)
make clean GCE-debug (to build the GNU C debug dll with C++ exception handling)
make clean GC-inlined-debug (to build the GNU C inlined debug dll with C cleanup code)
make clean GCE-inlined-debug (to build the GNU C inlined debug dll with C++ exception handling)
make clean GC-static-debug (to build the GNU C inlined static debug lib with C cleanup code)
The pre-built dlls are normally built using the *-inlined targets.
You can run the testsuite by changing to the "tests" directory and
running make for help information. E.g.:
$ cd tests
$ make
Run one of the following command lines:
make clean GC (to test using GC dll with C (no EH) applications)
make clean GCX (to test using GC dll with C++ (EH) applications)
make clean GCE (to test using GCE dll with C++ (EH) applications)
make clean GC-bench (to benchtest using GNU C dll with C cleanup code)
make clean GCE-bench (to benchtest using GNU C dll with C++ exception handling)
make clean GC-static (to test using GC static lib with C (no EH) applications)
Building under Linux using the Mingw32 cross development tools
--------------------------------------------------------------
You can build the library without leaving Linux by using the Mingw32 cross
development toolchain. See http://www.libsdl.org/extras/win32/cross/ for
tools and info. The GNUmakefile contains some support for this, for example:
make CROSS=i386-mingw32msvc- clean GC-inlined
will build pthreadGCn.dll and libpthreadGCn.a (n=version#), provided your
cross-tools/bin directory is in your PATH (or use the cross-make.sh script
at the URL above).
Building the library as a statically linkable library
-----------------------------------------------------
General: PTW32_STATIC_LIB must be defined for both the library build and the
application build. The makefiles supplied and used by the following 'make'
command lines will define this for you.
MSVC (creates pthreadVCn.lib as a static link lib):
nmake clean VC-static
MinGW32 (creates libpthreadGCn.a as a static link lib):
make clean GC-static
Define PTW32_STATIC_LIB when building your application. Also, your
application must call a two non-portable routines to initialise the
some state on startup and cleanup before exit. One other routine needs
to be called to cleanup after any Win32 threads have called POSIX API
routines. See README.NONPORTABLE or the html reference manual pages for
details on these routines:
BOOL pthread_win32_process_attach_np (void);
BOOL pthread_win32_process_detach_np (void);
BOOL pthread_win32_thread_attach_np (void); // Currently a no-op
BOOL pthread_win32_thread_detach_np (void);
The tests makefiles have the same targets but only check that the
static library is statically linkable. They don't run the full
testsuite. To run the full testsuite, build the dlls and run the
dll test targets.
Building the library under Cygwin
---------------------------------
Cygwin is implementing it's own POSIX threads routines and these
will be the ones to use if you develop using Cygwin.
Ready to run binaries
---------------------
For convenience, the following ready-to-run files can be downloaded
from the FTP site (see under "Availability" below):
pthread.h
semaphore.h
sched.h
pthreadVC.dll - built with MSVC compiler using C setjmp/longjmp
pthreadVC.lib
pthreadVCE.dll - built with MSVC++ compiler using C++ EH
pthreadVCE.lib
pthreadVSE.dll - built with MSVC compiler using SEH
pthreadVSE.lib
pthreadGC.dll - built with Mingw32 GCC
libpthreadGC.a - derived from pthreadGC.dll
pthreadGCE.dll - built with Mingw32 G++
libpthreadGCE.a - derived from pthreadGCE.dll
As of August 2003 pthreads-win32 pthreadG* versions are built and tested
using the MinGW + MsysDTK environment current as of that date or later.
The following file MAY be needed for older MinGW environments.
gcc.dll - needed to build and run applications that use
pthreadGCE.dll.
Building applications with GNU compilers
----------------------------------------
If you're using pthreadGC.dll:
With the three header files, pthreadGC.dll and libpthreadGC.a in the
same directory as your application myapp.c, you could compile, link
and run myapp.c under Mingw32 as follows:
gcc -o myapp.exe myapp.c -I. -L. -lpthreadGC
myapp
Or put pthreadGC.dll in an appropriate directory in your PATH,
put libpthreadGC.a in your system lib directory, and
put the three header files in your system include directory,
then use:
gcc -o myapp.exe myapp.c -lpthreadGC
myapp
If you're using pthreadGCE.dll:
With the three header files, pthreadGCE.dll, gcc.dll and libpthreadGCE.a
in the same directory as your application myapp.c, you could compile,
link and run myapp.c under Mingw32 as follows:
gcc -x c++ -o myapp.exe myapp.c -I. -L. -lpthreadGCE
myapp
Or put pthreadGCE.dll and gcc.dll in an appropriate directory in
your PATH, put libpthreadGCE.a in your system lib directory, and
put the three header files in your system include directory,
then use:
gcc -x c++ -o myapp.exe myapp.c -lpthreadGCE
myapp

deps/uv/deps/pthread-win32/README.Borland

@ -1,57 +0,0 @@
In ptw32_InterlockedCompareExchange.c, I've added a section for
Borland's compiler; it's identical to that for the MS compiler except
that it uses /* ... */ comments instead of ; comments.
[RPJ: need to define HAVE_TASM32 in config.h to use the above.]
The other file is a makefile suitable for use with Borland's compiler
(run "make -fBmakefile" in the directory). It builds a single version
of the library, pthreadBC.dll and the corresponding pthreadBC.lib
import library, which is comparable to the pthreadVC version; I can't
personally see any demand for the versions that include structured or
C++ exception cancellation handling so I haven't attempted to build
those versions of the library. (I imagine a static version might be
of use to some, but we can't legally use that on my commercial
projects so I can't try that out, unfortunately.)
[RPJ: Added tests\Bmakefile as well.]
Borland C++ doesn't define the ENOSYS constant used by pthreads-win32;
rather than make more extensive patches to the pthreads-win32 source I
have a mostly-arbitrary constant for it in the makefile. However this
doesn't make it visible to the application using the library, so if
anyone actually wants to use this constant in their apps (why?)
someone might like to make a seperate NEED_BCC_something define to add
this stuff.
The makefile also #defines EDEADLK as EDEADLOCK, _timeb as timeb, and
_ftime as ftime, to deal with the minor differences between the two
RTLs' naming conventions, and sets the compiler flags as required to
get a normal compile of the library.
[RPJ: Moved errno values and _timeb etc to pthread.h, so apps will also
use them.]
(While I'm on the subject, the reason Borland users should recompile
the library, rather than using the impdef/implib technique suggested
previously on the mailing list, is that a) the errno constants are
different, so the results returned by the pthread_* functions can be
meaningless, and b) the errno variable/pseudo-variable itself is
different in the MS & BCC runtimes, so you can't access the
pthreadVC's errno from a Borland C++-compiled host application
correctly - I imagine there are other potential problems from the RTL
mismatch too.)
[RPJ: Make sure you use the same RTL in both dll and application builds.
The dll and tests Bmakefiles use cw32mti.lib. Having some trouble with
memory read exceptions running the test suite using BCC55.]

Will

This file documents non-portable functions and other issues.
Non-portable functions included in pthreads-win32
-------------------------------------------------
BOOL
pthread_win32_test_features_np(int mask)
This routine allows an application to check which
run-time auto-detected features are available within
the library.
The possible features are:
PTW32_SYSTEM_INTERLOCKED_COMPARE_EXCHANGE
Return TRUE if the native version of
InterlockedCompareExchange() is being used.
This feature is not meaningful in recent
library versions as MSVC builds only support
system implemented ICE. Note that all Mingw
builds use inlined asm versions of all the
Interlocked routines.
PTW32_ALERTABLE_ASYNC_CANCEL
Return TRUE is the QueueUserAPCEx package
QUSEREX.DLL is available and the AlertDrv.sys
driver is loaded into Windows, providing
alertable (pre-emptive) asyncronous threads
cancelation. If this feature returns FALSE
then the default async cancel scheme is in
use, which cannot cancel blocked threads.
Features may be Or'ed into the mask parameter, in which case
the routine returns TRUE if any of the Or'ed features would
return TRUE. At this stage it doesn't make sense to Or features
but it may some day.
void *
pthread_timechange_handler_np(void *)
To improve tolerance against operator or time service
initiated system clock changes.
This routine can be called by an application when it
receives a WM_TIMECHANGE message from the system. At
present it broadcasts all condition variables so that
waiting threads can wake up and re-evaluate their
conditions and restart their timed waits if required.
It has the same return type and argument type as a
thread routine so that it may be called directly
through pthread_create(), i.e. as a separate thread.
Parameters
Although a parameter must be supplied, it is ignored.
The value NULL can be used.
Return values
It can return an error EAGAIN to indicate that not
all condition variables were broadcast for some reason.
Otherwise, 0 is returned.
If run as a thread, the return value is returned
through pthread_join().
The return value should be cast to an integer.
HANDLE
pthread_getw32threadhandle_np(pthread_t thread);
Returns the win32 thread handle that the POSIX
thread "thread" is running as.
Applications can use the win32 handle to set
win32 specific attributes of the thread.
DWORD
pthread_getw32threadid_np (pthread_t thread)
Returns the Windows native thread ID that the POSIX
thread "thread" is running as.
Only valid when the library is built where
! (defined(__MINGW64__) || defined(__MINGW32__)) || defined (__MSVCRT__) || defined (__DMC__)

int
pthread_mutexattr_setkind_np(pthread_mutexattr_t * attr, int kind)

pthread_mutexattr_getkind_np(pthread_mutexattr_t * attr, int *kind)
These two routines are included for Linux compatibility
and are direct equivalents to the standard routines
pthread_mutexattr_settype

pthread_mutexattr_setkind_np accepts the following

PTHREAD_MUTEX_FAST_NP
PTHREAD_MUTEX_ERRORCHECK_NP

PTHREAD_MUTEX_NORMAL

int
pthread_delay_np (const struct timespec *interval);
This routine causes a thread to delay execution for a specific period of time.
This period ends at the current time plus the specified interval. The routine
will not return before the end of the period is reached, but may return an
arbitrary amount of time after the period has gone by. This can be due to
system load, thread priorities, and system timer granularity.
Specifying an interval of zero (0) seconds and zero (0) nanoseconds is
allowed and can be used to force the thread to give up the processor or to
deliver a pending cancelation request.
This routine is a cancelation point.
The timespec structure contains the following two fields:
tv_sec is an integer number of seconds.
tv_nsec is an integer number of nanoseconds.
Return Values
If an error condition occurs, this routine returns an integer value
indicating the type of error. Possible return values are as follows:
0 Successful completion.
[EINVAL] The value specified by interval is invalid.
int
pthread_num_processors_np (void)
This routine (found on HPUX systems) returns the number of processors
in the system. This implementation actually returns the number of
processors available to the process, which can be a lower number
than the system's number, depending on the process's affinity mask.
BOOL
pthread_win32_process_attach_np (void);
BOOL
pthread_win32_process_detach_np (void);
BOOL
pthread_win32_thread_attach_np (void);
BOOL
pthread_win32_thread_detach_np (void);
These functions contain the code normally run via dllMain
when the library is used as a dll but which need to be
called explicitly by an application when the library
is statically linked. As of version 2.9.0 of the library, static
builds using either MSC or GCC will call pthread_win32_process_*
automatically at application startup and exit respectively.
Otherwise, you will need to call pthread_win32_process_attach_np()
before you can call any pthread routines when statically linking.
You should call pthread_win32_process_detach_np() before
exiting your application to clean up.
pthread_win32_thread_attach_np() is currently a no-op, but
pthread_win32_thread_detach_np() is needed to clean up
the implicit pthread handle that is allocated to a Win32 thread if
it calls any pthreads routines. Call this routine when the
Win32 thread exits.
Threads created through pthread_create() do not need to call
pthread_win32_thread_detach_np().
These functions invariably return TRUE except for
pthread_win32_process_attach_np() which will return FALSE
if pthreads-win32 initialisation fails.
int
pthreadCancelableWait (HANDLE waitHandle);
int
pthreadCancelableTimedWait (HANDLE waitHandle, DWORD timeout);
These two functions provide hooks into the pthread_cancel
mechanism that will allow you to wait on a Windows handle
and make it a cancellation point. Both functions block
until either the given w32 handle is signaled, or
pthread_cancel has been called. It is implemented using
WaitForMultipleObjects on 'waitHandle' and a manually
reset w32 event used to implement pthread_cancel.
Non-portable issues
-------------------
Thread priority
POSIX defines a single contiguous range of numbers that determine a
thread's priority. Win32 defines priority classes and priority
levels relative to these classes. Classes are simply priority base
levels that the defined priority levels are relative to such that,
changing a process's priority class will change the priority of all
of it's threads, while the threads retain the same relativity to each
other.
A Win32 system defines a single contiguous monotonic range of values
that define system priority levels, just like POSIX. However, Win32
restricts individual threads to a subset of this range on a
per-process basis.
The following table shows the base priority levels for combinations
of priority class and priority value in Win32.

Windows NT: Values -7, -6, -5, -4, -3, 3, 4, 5, and 6 are not supported.
As you can see, the real priority levels available to any individual
Win32 thread are non-contiguous.
An application using pthreads-win32 should not make assumptions about
the numbers used to represent thread priority levels, except that they
are monotonic between the values returned by sched_get_priority_min()
and sched_get_priority_max(). E.g. Windows 95, 98, NT, 2000, XP make
available a non-contiguous range of numbers between -15 and 15, while
at least one version of WinCE (3.0) defines the minimum priority
(THREAD_PRIORITY_LOWEST) as 5, and the maximum priority
(THREAD_PRIORITY_HIGHEST) as 1.
Internally, pthreads-win32 maps any priority levels between
THREAD_PRIORITY_IDLE and THREAD_PRIORITY_LOWEST to THREAD_PRIORITY_LOWEST,
or between THREAD_PRIORITY_TIME_CRITICAL and THREAD_PRIORITY_HIGHEST to
THREAD_PRIORITY_HIGHEST. Currently, this also applies to
REALTIME_PRIORITY_CLASSi even if levels -7, -6, -5, -4, -3, 3, 4, 5, and 6
are supported.
If it wishes, a Win32 application using pthreads-win32 can use the Win32
defined priority macros THREAD_PRIORITY_IDLE through
THREAD_PRIORITY_TIME_CRITICAL.
The opacity of the pthread_t datatype
-------------------------------------
and possible solutions for portable null/compare/hash, etc
----------------------------------------------------------
Because pthread_t is an opague datatype an implementation is permitted to define
pthread_t in any way it wishes. That includes defining some bits, if it is
scalar, or members, if it is an aggregate, to store information that may be
extra to the unique identifying value of the ID. As a result, pthread_t values
may not be directly comparable.
If you want your code to be portable you must adhere to the following contraints:
1) Don't assume it is a scalar data type, e.g. an integer or pointer value. There
are several other implementations where pthread_t is also a struct. See our FAQ
Question 11 for our reasons for defining pthread_t as a struct.
2) You must not compare them using relational or equality operators. You must use
the API function pthread_equal() to test for equality.
3) Never attempt to reference individual members.
The problem
Certain applications would like to be able to access only the 'pure' pthread_t
id values, primarily to use as keys into data structures to manage threads or
thread-related data, but this is not possible in a maximally portable and
standards compliant way for current POSIX threads implementations.
For implementations that define pthread_t as a scalar, programmers often employ
direct relational and equality operators on pthread_t. This code will break when
ported to an implementation that defines pthread_t as an aggregate type.
For implementations that define pthread_t as an aggregate, e.g. a struct,
programmers can use memcmp etc., but then face the prospect that the struct may
include alignment padding bytes or bits as well as extra implementation-specific
members that are not part of the unique identifying value.
[While this is not currently the case for pthreads-win32, opacity also
means that an implementation is free to change the definition, which should
generally only require that applications be recompiled and relinked, not
rewritten.]
Doesn't the compiler take care of padding?
The C89 and later standards only effectively guarrantee element-by-element
equivalence following an assignment or pass by value of a struct or union,
therefore undefined areas of any two otherwise equivalent pthread_t instances
can still compare differently, e.g. attempting to compare two such pthread_t
variables byte-by-byte, e.g. memcmp(&t1, &t2, sizeof(pthread_t) may give an
incorrect result. In practice I'm reasonably confident that compilers routinely
also copy the padding bytes, mainly because assignment of unions would be far
too complicated otherwise. But it just isn't guarranteed by the standard.
Illustration:
We have two thread IDs t1 and t2
pthread_t t1, t2;
In an application we create the threads and intend to store the thread IDs in an
ordered data structure (linked list, tree, etc) so we need to be able to compare
them in order to insert them initially and also to traverse.
Suppose pthread_t contains undefined padding bits and our compiler copies our
pthread_t [struct] element-by-element, then for the assignment:
pthread_t temp = t1;
temp and t1 will be equivalent and correct but a byte-for-byte comparison such as
memcmp(&temp, &t1, sizeof(pthread_t)) == 0 may not return true as we expect because
the undefined bits may not have the same values in the two variable instances.
Similarly if passing by value under the same conditions.
If, on the other hand, the undefined bits are at least constant through every
assignment and pass-by-value then the byte-for-byte comparison
memcmp(&temp, &t1, sizeof(pthread_t)) == 0 will always return the expected result.
How can we force the behaviour we need?
Solutions
Adding new functions to the standard API or as non-portable extentions is
the only reliable and portable way to provide the necessary operations.
Remember also that POSIX is not tied to the C language. The most common
functions that have been suggested are:
pthread_null()
pthread_compare()
pthread_hash()
A single more general purpose function could also be defined as a
basis for at least the last two of the above functions.
First we need to list the freedoms and constraints with restpect
to pthread_t so that we can be sure our solution is compatible with the
standard.
What is known or may be deduced from the standard:
1) pthread_t must be able to be passed by value, so it must be a single object.
2) from (1) it must be copyable so cannot embed thread-state information, locks
or other volatile objects required to manage the thread it associates with.
3) pthread_t may carry additional information, e.g. for debugging or to manage
itself.
4) there is an implicit requirement that the size of pthread_t is determinable
at compile-time and size-invariant, because it must be able to copy the object
(i.e. through assignment and pass-by-value). Such copies must be genuine
duplicates, not merely a copy of a pointer to a common instance such as
would be the case if pthread_t were defined as an array.
Suppose we define the following function:
/* This function shall return it's argument */
pthread_t* pthread_normalize(pthread_t* thread);
For scalar or aggregate pthread_t types this function would simply zero any bits
within the pthread_t that don't uniquely identify the thread, including padding,
such that client code can return consistent results from operations done on the
result. If the additional bits are a pointer to an associate structure then
this function would ensure that the memory used to store that associate
structure does not leak. After normalization the following compare would be
valid and repeatable:
memcmp(pthread_normalize(&t1),pthread_normalize(&t2),sizeof(pthread_t))
Note 1: such comparisons are intended merely to order and sort pthread_t values
and allow them to index various data structures. They are not intended to reveal
anything about the relationships between threads, like startup order.
Note 2: the normalized pthread_t is also a valid pthread_t that uniquely
identifies the same thread.
Advantages:
1) In most existing implementations this function would reduce to a no-op that
emits no additional instructions, i.e after in-lining or optimisation, or if
defined as a macro:
#define pthread_normalise(tptr) (tptr)
2) This single function allows an application to portably derive
application-level versions of any of the other required functions.
3) It is a generic function that could enable unanticipated uses.
Disadvantages:
1) Less efficient than dedicated compare or hash functions for implementations
that include significant extra non-id elements in pthread_t.
2) Still need to be concerned about padding if copying normalized pthread_t.
See the later section on defining pthread_t to neutralise padding issues.
Generally a pthread_t may need to be normalized every time it is used,
which could have a significant impact. However, this is a design decision
for the implementor in a competitive environment. An implementation is free
to define a pthread_t in a way that minimises or eliminates padding or
renders this function a no-op.
Hazards:
1) Pass-by-reference directly modifies 'thread' so the application must
synchronise access or ensure that the pointer refers to a copy. The alternative
of pass-by-value/return-by-value was considered but then this requires two copy
operations, disadvantaging implementations where this function is not a no-op
in terms of speed of execution. This function is intended to be used in high
frequency situations and needs to be efficient, or at least not unnecessarily
inefficient. The alternative also sits awkwardly with functions like memcmp.
2) [Non-compliant] code that uses relational and equality operators on
arithmetic or pointer style pthread_t types would need to be rewritten, but it
should be rewritten anyway.

A pthread_t type change proposal to neutralise the effects of padding
Even if pthread_nornalize() is available, padding is still a problem because
the standard only garrantees element-by-element equivalence through
copy operations (assignment and pass-by-value). So padding bit values can
still change randomly after calls to pthread_normalize().
[I suspect that most compilers take the easy path and always byte-copy anyway,
partly because it becomes too complex to do (e.g. unions that contain sub-aggregates)
but also because programmers can easily design their aggregates to minimise and
often eliminate padding].
How can we eliminate the problem of padding bytes in structs? Could
defining pthread_t as a union rather than a struct provide a solution?
In fact, the Linux pthread.h defines most of it's pthread_*_t objects (but not
pthread_t itself) as unions, possibly for this and/or other reasons. We'll
borrow some element naming from there but the ideas themselves are well known
- the __align element used to force alignment of the union comes from K&R's
storage allocator example.
/* Essentially our current pthread_t renamed */
typedef struct {
struct thread_state_t * __p;
long __x; /* sequence counter */
} thread_id_t;
Ensuring that the last element in the above struct is a long ensures that the
overall struct size is a multiple of sizeof(long), so there should be no trailing
padding in this struct or the union we define below.
(Later we'll see that we can handle internal but not trailing padding.)
/* New pthread_t */
typedef union {
char __size[sizeof(thread_id_t)]; /* array as the first element */
thread_id_t __tid;
long __align; /* Ensure that the union starts on long boundary */
} pthread_t;
This guarrantees that, during an assignment or pass-by-value, the compiler copies
every byte in our thread_id_t because the compiler guarrantees that the __size
array, which we have ensured is the equal-largest element in the union, retains
equivalence.
This means that pthread_t values stored, assigned and passed by value will at least
carry the value of any undefined padding bytes along and therefore ensure that
those values remain consistent. Our comparisons will return consistent results and
our hashes of [zero initialised] pthread_t values will also return consistent
results.
We have also removed the need for a pthread_null() function; we can initialise
at declaration time or easily create our own const pthread_t to use in assignments
later:
const pthread_t null_tid = {0}; /* braces are required */
pthread_t t;
...
t = null_tid;
Note that we don't have to explicitly make use of the __size array at all. It's
there just to force the compiler behaviour we want.
Partial solutions without a pthread_normalize function
An application-level pthread_null and pthread_compare proposal
(and pthread_hash proposal by extention)
In order to deal with the problem of scalar/aggregate pthread_t type disparity in
portable code I suggest using an old-fashioned union, e.g.:
Contraints:
- there is no padding, or padding values are preserved through assignment and
pass-by-value (see above);
- there are no extra non-id values in the pthread_t.
Example 1: A null initialiser for pthread_t variables...
typedef union {
unsigned char b[sizeof(pthread_t)];
pthread_t t;
} init_t;
const init_t initial = {0};
pthread_t tid = initial.t; /* init tid to all zeroes */
Example 2: A comparison function for pthread_t values
typedef union {
unsigned char b[sizeof(pthread_t)];
pthread_t t;
} pthcmp_t;
int pthcmp(pthread_t left, pthread_t right)
{
/*
* Compare two pthread handles in a way that imposes a repeatable but arbitrary
* ordering on them.
* I.e. given the same set of pthread_t handles the ordering should be the same
* each time but the order has no particular meaning other than that. E.g.
* the ordering does not imply the thread start sequence, or any other
* relationship between threads.
*
* Return values are:
* 1 : left is greater than right
* 0 : left is equal to right
* -1 : left is less than right
*/
int i;
pthcmp_t L, R;
L.t = left;
R.t = right;
for (i = 0; i < sizeof(pthread_t); i++)
{
if (L.b[i] > R.b[i])
return 1;
else if (L.b[i] < R.b[i])
return -1;
}
return 0;
}
It has been pointed out that the C99 standard allows for the possibility that
integer types also may include padding bits, which could invalidate the above
method. This addition to C99 was specifically included after it was pointed
out that there was one, presumably not particularly well known, architecture
that included a padding bit in it's 32 bit integer type. See section 6.2.6.2
of both the standard and the rationale, specifically the paragraph starting at
line 16 on page 43 of the rationale.
An aside
Certain compilers, e.g. gcc and one of the IBM compilers, include a feature
extention: provided the union contains a member of the same type as the
object then the object may be cast to the union itself.
We could use this feature to speed up the pthrcmp() function from example 2
above by casting rather than assigning the pthread_t arguments to the union, e.g.:
int pthcmp(pthread_t left, pthread_t right)
{
/*
* Compare two pthread handles in a way that imposes a repeatable but arbitrary
* ordering on them.
* I.e. given the same set of pthread_t handles the ordering should be the same
* each time but the order has no particular meaning other than that. E.g.
* the ordering does not imply the thread start sequence, or any other
* relationship between threads.
*
* Return values are:
* 1 : left is greater than right
* 0 : left is equal to right
* -1 : left is less than right
*/
int i;
for (i = 0; i < sizeof(pthread_t); i++)
{
if (((pthcmp_t)left).b[i] > ((pthcmp_t)right).b[i])
return 1;
else if (((pthcmp_t)left).b[i] < ((pthcmp_t)right).b[i])
return -1;
}
return 0;
}
Result thus far
We can't remove undefined bits if they are there in pthread_t already, but we have
attempted to render them inert for comparison and hashing functions by making them
consistent through assignment, copy and pass-by-value.
Note: Hashing pthread_t values requires that all pthread_t variables be initialised
to the same value (usually all zeros) before being assigned a proper thread ID, i.e.
to ensure that any padding bits are zero, or at least the same value for all
pthread_t. Since all pthread_t values are generated by the library in the first
instance this need not be an application-level operation.
Conclusion
I've attempted to resolve the multiple issues of type opacity and the possible
presence of undefined bits and bytes in pthread_t values, which prevent
applications from comparing or hashing pthread handles.
Two complimentary partial solutions have been proposed, one an application-level
scheme to handle both scalar and aggregate pthread_t types equally, plus a
definition of pthread_t itself that neutralises padding bits and bytes by
coercing semantics out of the compiler to eliminate variations in the values of
padding bits.
I have not provided any solution to the problem of handling extra values embedded
in pthread_t, e.g. debugging or trap information that an implementation is entitled
to include. Therefore none of this replaces the portability and flexibility of API
functions but what functions are needed? The threads standard is unlikely to
include that can be implemented by a combination of existing features and more
generic functions (several references in the threads rationale suggest this.
Therefore I propose that the following function could replace the several functions
that have been suggested in conversations:
pthread_t * pthread_normalize(pthread_t * handle);
For most existing pthreads implementations this function, or macro, would reduce to
a no-op with zero call overhead.

Current known problems
----------------------
Library build:
The Watcom compiler uses a different default call convention to MS C or GNU C and so
applications are not compatible with pthreadVC.dll etc using pre 2003-10-14 versions
of pthread.h, sched.h, or semaphore.h. The cdecl attribute can be used on exposed
function prototypes to force compatibility with MS C built DLLs.
However, there appear to be other incompatibilities. Errno.h, for example, defines
different values for the standard C and POSIX errors to those defined by the MS C
errno.h. It may be that references to Watcom's threads compatible 'errno' do set
and return translated numbers consistently, but I have not verified this.
Watcom defines errno as a dereferenced pointer returned by the function
_get_errno_ptr(). This is similar to both the MS and GNU C environments for
multithreaded use. However, the Watcom version appears to have a number of problems:
- different threads return the same pointer value. Compare with the MS and GNU C
versions which correctly return different values (since each thread must maintain
a thread specific errno value).
- an errno value set within the DLL appears as zero in the application even though
both share the same thread.
Therefore applications built using the Watcom compiler may need to use
a Watcom built version of the library (pthreadWC.dll). If this is the case, then
the cdecl function attribute should not be required.
Application builds:
The test suite fails with the Watcom compiler.
Test semaphore1.c fails for pthreadWC.dll because errno returns 0 instead of EAGAIN.

deps/uv/deps/pthread-win32/WinCE-PORT

@ -1,222 +0,0 @@
NOTE: The comments in this file relate to the original WinCE port
done by Tristan Savatier. The semaphore routines have been
completely rewritten since (2005-04-25), having been progressively
broken more and more by changes to the library. All of the semaphore
routines implemented for W9x/WNT/2000 and up should now also work for
WinCE. Also, pthread_mutex_timedlock should now work.
Additional WinCE updates have been applied since this as well. Check the
ChangeLog file and search for WINCE for example. (2007-01-07)
[RPJ]
----
Some interesting news:
I have been able to port pthread-win32 to Windows-CE,
which uses a subset of the WIN32 API.
Since we intend to keep using pthread-win32 for our
Commercial WinCE developments, I would be very interested
if WinCE support could be added to the main source tree
of pthread-win32. Also, I would like to be credited
for this port :-)
Now, here is the story...
The port was performed and tested on a Casio "Cassiopeia"
PalmSize PC, which runs a MIP processor. The OS in the
Casio is WinCE version 2.11, but I used VC++ 6.0 with
the WinCE SDK for version 2.01.
I used pthread-win32 to port a heavily multithreaded
commercial application (real-time MPEG video player)
from Linux to WinCE. I consider the changes that
I have done to be quite well tested.
Overall the modifications that we had to do are minor.
The WinCE port were based on pthread-win32-snap-1999-05-30,
but I am certain that they can be integrated very easiely
to more recent versions of the source.
I have attached the modified source code:
pthread-win32-snap-1999-05-30-WinCE.
All the changes do not affect the code compiled on non-WinCE
environment, provided that the macros used for WinCE compilation
are not used, of course!
Overall description of the WinCE port:
-------------------------------------
Most of the changes had to be made in areas where
pthread-win32 was relying on some standard-C librairies
(e.g. _ftime, calloc, errno), which are not available
on WinCE. We have changed the code to use native Win32
API instead (or in some cases we made wrappers).
The Win32 Semaphores are not available,
so we had to re-implement Semaphores using mutexes
and events.
Limitations / known problems of the WinCE port:
----------------------------------------------
Not all the semaphore routines have been ported
(semaphores are defined by Posix but are not part
pf pthread). I have just done enough to make
pthread routines (that rely internally on semaphores)
work, like signal conditions.
I noticed that the Win32 threads work slightly
differently on WinCE. This may have some impact
on some tricky parts of pthread-win32, but I have
not really investigated. For example, on WinCE,
the process is killed if the main thread falls off
the bottom (or calls pthread_exit), regardless
of the existence of any other detached thread.
Microsoft manual indicates that this behavior is
deffirent from that of Windows Threads for other
Win32 platforms.
Detailed descriptions of the changes and rationals:
------------------------------------
- use a new macro NEED_ERRNO.
If defined, the code in errno.c that defines a reentrant errno
is compiled, regardless of _MT and _REENTRANT.
Rational: On WinCE, there is no support for <stdio.h>, <errno.h> or
any other standard C library, i.e. even if _MT or _REENTRANT
is defined, errno is not provided by any library. NEED_ERRNO
must be set to compile for WinCE.
------------------------------------
- In implement.h, change #include <semaphore.h> to #include "semaphore.h".
Rational: semaphore.h is provided in pthread-win32 and should not
be searched in the systems standard include. would not compile.
This change does not seem to create problems on "classic" win32
(e.g. win95).
------------------------------------
- use a new macro NEED_CALLOC.
If defined, some code in misc.c will provide a replacement
for calloc, which is not available on Win32.
------------------------------------
- use a new macro NEED_CREATETHREAD.
If defined, implement.h defines the macro _beginthreadex
and _endthreadex.
Rational: On WinCE, the wrappers _beginthreadex and _endthreadex
do not exist. The native Win32 routines must be used.
------------------------------------
- in misc.c:
#ifdef NEED_DUPLICATEHANDLE
/* DuplicateHandle does not exist on WinCE */
self->threadH = GetCurrentThread();
#else
if( !DuplicateHandle(
GetCurrentProcess(),
GetCurrentThread(),
GetCurrentProcess(),
&self->threadH,
0,
FALSE,
DUPLICATE_SAME_ACCESS ) )
{
free( self );
return (NULL);
}
#endif
Rational: On WinCE, DuplicateHandle does not exist. I could not understand
why DuplicateHandle must be used. It seems to me that getting the current
thread handle with GetCurrentThread() is sufficient, and it seems to work
perfectly fine, so maybe DuplicateHandle was just plain useless to begin with ?
------------------------------------
- In private.c, added some code at the beginning of ptw32_processInitialize
to detect the case of multiple calls to ptw32_processInitialize.
Rational: In order to debug pthread-win32, it is easier to compile
it as a regular library (it is not possible to debug DLL's on winCE).
In that case, the application must call ptw32_rocessInitialize()
explicitely, to initialize pthread-win32. It is safer in this circumstance
to handle the case where ptw32_processInitialize() is called on
an already initialized library:
int
ptw32_processInitialize (void)
{
if (ptw32_processInitialized) {
/*
* ignore if already initialized. this is useful for
* programs that uses a non-dll pthread
* library. such programs must call ptw32_processInitialize() explicitely,
* since this initialization routine is automatically called only when
* the dll is loaded.
*/
return TRUE;
}
ptw32_processInitialized = TRUE;
[...]
}
------------------------------------
- in private.c, if macro NEED_FTIME is defined, add routines to
convert timespec_to_filetime and filetime_to_timespec, and modified
code that was using _ftime() to use Win32 API instead.
Rational: _ftime is not available on WinCE. It is necessary to use
the native Win32 time API instead.
Note: the routine timespec_to_filetime is provided as a convenience and a mean
to test that filetime_to_timespec works, but it is not used by the library.
------------------------------------
- in semaphore.c, if macro NEED_SEM is defined, add code for the routines
_increase_semaphore and _decrease_semaphore, and modify significantly
the implementation of the semaphores so that it does not use CreateSemaphore.
Rational: CreateSemaphore is not available on WinCE. I had to re-implement
semaphores using mutexes and Events.
Note: Only the semaphore routines that are used by pthread are implemented
(i.e. signal conditions rely on a subset of the semaphores routines, and
this subset works). Some other semaphore routines (e.g. sem_trywait) are
not yet supported on my WinCE port (and since I don't need them, I am not
planning to do anything about them).
------------------------------------
- in tsd.c, changed the code that defines TLS_OUT_OF_INDEXES
/* TLS_OUT_OF_INDEXES not defined on WinCE */
#ifndef TLS_OUT_OF_INDEXES
#define TLS_OUT_OF_INDEXES 0xffffffff
#endif
Rational: TLS_OUT_OF_INDEXES is not defined in any standard include file
on WinCE.
------------------------------------
- added file need_errno.h
Rational: On WinCE, there is no errno.h file. need_errno.h is just a
copy of windows version of errno.h, with minor modifications due to the fact
that some of the error codes are defined by the WinCE socket library.
In pthread.h, if NEED_ERRNO is defined, the file need_errno.h is
included (instead of <errno.h>).

# Usage:
# Set to any value in the range: 0 <= value < 2^wordsize.
# Set to 0 to emulate reusable thread ID behaviour like Linux or *BSD.
# Set to 1 for unique thread IDs like Solaris (this is the default).

/*
* Purpose:
* This structure creates an association between a thread and a key.
* It is used to implement the implicit invocation of a user defined
* destroy routine for thread specific data registered by a user upon
* exiting a thread.
*
* Graphically, the arrangement is as follows, where:
*
* K - Key with destructor
* (head of chain is key->threads)
* T - Thread that has called pthread_setspecific(Kn)
* (head of chain is thread->keys)
* A - Association. Each association is a node at the
* intersection of two doubly-linked lists.
*
* T1 T2 T3
* | | |
* | | |
* K1 -----+-----A-----A----->
* | | |
* | | |
* K2 -----A-----A-----+----->
* | | |
* | | |
* K3 -----A-----+-----A----->
* | | |
* | | |
* V V V
*
* Access to the association is guarded by two locks: the key's
* general lock (guarding the row) and the thread's general
* lock (guarding the column). This avoids the need for a
* dedicated lock for each association, which not only consumes
* more handles but requires that the lock resources persist
* until both the key is deleted and the thread has called the
* destructor. The two-lock arrangement allows those resources
* to be freed as soon as either thread or key is concluded.
*
* To avoid deadlock, whenever both locks are required both the
* key and thread locks are acquired consistently in the order
* "key lock then thread lock". An exception to this exists
* when a thread calls the destructors, however, this is done
* carefully (but inelegantly) to avoid deadlock.
*
* An association is created when a thread first calls
* pthread_setspecific() on a key that has a specified
* destructor.
*
* An association is destroyed either immediately after the
* thread calls the key destructor function on thread exit, or
* when the key is deleted.
*
* Attributes:
* thread
* reference to the thread that owns the
* association. This is actually the pointer to the
* thread struct itself. Since the association is
* destroyed before the thread exits, this can never
* point to a different logical thread to the one that
* created the assoc, i.e. after thread struct reuse.
*
* key
* reference to the key that owns the association.
*
* nextKey
* The pthread_t->keys attribute is the head of a
* chain of associations that runs through the nextKey
* link. This chain provides the 1 to many relationship
* between a pthread_t and all pthread_key_t on which
* it called pthread_setspecific.
*
* prevKey
* Similarly.
*
* nextThread
* The pthread_key_t->threads attribute is the head of
* a chain of associations that runs through the
* nextThreads link. This chain provides the 1 to many
* relationship between a pthread_key_t and all the
* PThreads that have called pthread_setspecific for
* this pthread_key_t.
*
* prevThread
* Similarly.
*
* Notes:
* 1) As soon as either the key or the thread is no longer
* referencing the association, it can be destroyed. The
* association will be removed from both chains.
*
* 2) Under WIN32, an association is only created by
* pthread_setspecific if the user provided a
* destroyRoutine when they created the key.

*
*
* DESCRIPTION
* This function destroys a condition variable.
*
* NOTES:
* 1) A condition variable can be destroyed
* immediately after all the threads that
* are blocked on it are awakened. e.g.
*
* struct list {
* pthread_mutex_t lm;
* ...
* }
*
* struct elt {
* key k;
* int busy;
* pthread_cond_t notbusy;
* ...
* }
*
*
* struct elt *
* list_find(struct list *lp, key k)
* {
* struct elt *ep;
*
* pthread_mutex_lock(&lp->lm);
* while ((ep = find_elt(l,k) != NULL) && ep->busy)
* pthread_cond_wait(&ep->notbusy, &lp->lm);
* if (ep != NULL)
* ep->busy = 1;
* pthread_mutex_unlock(&lp->lm);
* return(ep);
* }
*
* delete_elt(struct list *lp, struct elt *ep)
* {
* pthread_mutex_lock(&lp->lm);
* assert(ep->busy);
* ... remove ep from list ...
* ep->busy = 0;
* (A) pthread_cond_broadcast(&ep->notbusy);
* pthread_mutex_unlock(&lp->lm);
* (B) pthread_cond_destroy(&rp->notbusy);
* free(ep);
* }
*
* In this example, the condition variable
* and its list element may be freed (line B)
* immediately after all threads waiting for
* it are awakened (line A), since the mutex
* and the code ensure that no other thread
* can touch the element to be deleted.
*
* RESULTS
* 0 successfully released condition variable,
* EINVAL 'cond' is invalid,
* EBUSY 'cond' is in use,
*

/*
* pthread_delay_np
*
* DESCRIPTION
*
* This routine causes a thread to delay execution for a specific period of time.
* This period ends at the current time plus the specified interval. The routine
* will not return before the end of the period is reached, but may return an
* arbitrary amount of time after the period has gone by. This can be due to
* system load, thread priorities, and system timer granularity.
*
* Specifying an interval of zero (0) seconds and zero (0) nanoseconds is
* allowed and can be used to force the thread to give up the processor or to
* deliver a pending cancelation request.
*
* The timespec structure contains the following two fields:
*
* tv_sec is an integer number of seconds.
* tv_nsec is an integer number of nanoseconds.
*
* Return Values
*
* If an error condition occurs, this routine returns an integer value indicating
* the type of error. Possible return values are as follows:
*
* 0
* Successful completion.
* [EINVAL]
* The value specified by interval is invalid.
*
* Example
*
* The following code segment would wait for 5 and 1/2 seconds
*
* struct timespec tsWait;
* int intRC;
*
* tsWait.tv_sec = 5;
* tsWait.tv_nsec = 500000000L;
* intRC = pthread_delay_np(&tsWait);

/*
* From the Sun Multi-threaded Programming Guide
*
* robustness defines the behavior when the owner of the mutex terminates without unlocking the
* mutex, usually because its process terminated abnormally. The value of robustness that is
* defined in pthread.h is PTHREAD_MUTEX_ROBUST or PTHREAD_MUTEX_STALLED. The
* default value is PTHREAD_MUTEX_STALLED .
* PTHREAD_MUTEX_STALLED
* When the owner of the mutex terminates without unlocking the mutex, all subsequent calls
* to pthread_mutex_lock() are blocked from progress in an unspecified manner.
* PTHREAD_MUTEX_ROBUST
* When the owner of the mutex terminates without unlocking the mutex, the mutex is
* unlocked. The next owner of this mutex acquires the mutex with an error return of
* EOWNERDEAD.
* Note Your application must always check the return code from pthread_mutex_lock() for
* a mutex initialized with the PTHREAD_MUTEX_ROBUST attribute.
* The new owner of this mutex should make the state protected by the mutex consistent.
* This state might have been left inconsistent when the previous owner terminated.
* If the new owner is able to make the state consistent, call
* pthread_mutex_consistent() for the mutex before unlocking the mutex. This
* marks the mutex as consistent and subsequent calls to pthread_mutex_lock() and
* pthread_mutex_unlock() will behave in the normal manner.
* If the new owner is not able to make the state consistent, do not call
* pthread_mutex_consistent() for the mutex, but unlock the mutex.
* All waiters are woken up and all subsequent calls to pthread_mutex_lock() fail to
* acquire the mutex. The return code is ENOTRECOVERABLE. The mutex can be made
* consistent by calling pthread_mutex_destroy() to uninitialize the mutex, and calling
* pthread_mutex_int() to reinitialize the mutex.However, the state that was protected
* by the mutex remains inconsistent and some form of application recovery is required.
* If the thread that acquires the lock with EOWNERDEAD terminates without unlocking the
* mutex, the next owner acquires the lock with an EOWNERDEAD return code.
