* The pipe class is a simple RAII model for anonymous pipes. It |

* a pipe object that owns the two file handles associated to it: the |

* read end and the write end. |

* |
|

* These handles can be retrieved for modification according to |
|
||||
* file_handle semantics. Optionally, their ownership can be transferred |
|
||||
* to external \a file_handle objects which comes handy when the two |
|
||||
* ends need to be used in different places (i.e. after a POSIX fork() |
|
||||
* system call). |
|
||||
* |
|
||||
* Pipes can be copied following the same semantics as file handles. |
|
||||
* In other words, copying a %pipe object invalidates the source one. |

* Child process' input stream. |
|
||||
* |
|
||||
* The postream class represents an input communication channel with the |
|
||||
* child process. The child process reads data from this stream and the |
|
||||
* parent process can write to it through the postream object. In other |
|
||||
* words, from the child's point of view, the communication channel is an |
|
||||
* input one, but from the parent's point of view it is an output one; |
|
||||
* hence the confusing postream name. |
|
||||
* |
|
||||
* postream objects cannot be copied because they own the file handle |
|
||||
* they use to communicate with the child and because they buffer data |
|
||||
* that flows through the communication channel. |
|
||||
* |
|
||||
* A postream object behaves as a std::ostream stream in all senses. |
|
||||
* The class is only provided because it must provide a method to let |
|
||||
* the caller explicitly close the communication channel. |
|
||||
* |
|
||||
* \remark Blocking remarks: Functions that write data to this |
|
||||
* stream can block if the associated file handle blocks during |
|
||||
* the write. As this class is used to communicate with child |
|
||||
* processes through anonymous pipes, the most typical blocking |
|
||||
* condition happens when the child is not processing the data |
|
||||
* in the pipe's system buffer. When this happens, the buffer |
