zhelpers.h：　一个供C语言使用的ZMQ功能函数库。https://github.com/imatix/zguide/blob/master/examples/C/zhelpers.h　
pthread.h：　POSIX线程（POSIX threads），简称Pthreads，是线程的POSIX标准。该标准定义了创建和操纵线程的一整套API。在类Unix操作系统（Unix、Linux、Mac OS X等）中，都使用Pthreads作为操作系统的线程。Windows操作系统也有其移植版pthreads-win32。ftp://sourceware.org/pub/pthreads-win322
