you can call it like the above, where symbol is the coin, ep is the electrum server info pointer, the 0 is a callback ptr where 0 means to block till it is done
all the API calls have the same three args
if the callback ptr is &retjson, then on completion it will put the cJSON *ptr into it, so to spawn a bunch of calls you need to call with symbol,ep,&retjsons[i],...
