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。转载连接：https://blog.csdn.net/cry1994/article/details/79115394 下载源码源码主页： https://sourceware.org/pthreads-win32/ ftp地址： ftp://sourceware.org/pub/pthreads-win32 下载最新版本pthreads-w32-2-9-1-release.zip解压得到三个文件夹 Pre-built.2 Pre-build.2 里面包含了pthreads for win32 的头文件和库文件; pthreads.2 pthreads.2 里面包含了pthreads 的源代码； QueueUserAPCEx QueueUserAPCEx 里面是一个alert的driver，编译需要DDK 。Windows Device Driver Kit (NTDDK.h) 需要额外单独安装。直接使用or编译源码 1.直接使用 Pre-built

问题 I am using pthreads-win32 for threads on a Win32 Application. I am calculating the timespec using the first function posted here. The call to sem_timedwait() appears to be waiting for the specified ts time, however every time it completes I get the following message: Error waiting on semaphore: No error I have checked the file of sem_timedwait.c here, and they specify the same errno values and return values. Consequently, I do not know why it is exiting with this errno, and would like to know
