Pthreads on Microsoft Windows

Posix Threads API (pthreads) 是在並行編程中用到的非常普通的API，這套API包括許多非常基礎的同步方法，方便我們編寫高效的多線程程式。然而，Microsoft Windows 並不包含這樣的介面。幸運的是，這裡有一個開源的Windows平台上的 Pthread 實現。

下載下來僅僅是一個 winpthreads.h 檔案，把這個檔案包含在project中即可使用。

下面是使用這個API的一個例子，在Visual Studio 2008/2010/2012中編譯通過，在Windows 7/Windows 8上運行無誤：

#include <stdio.h>#include <tchar.h>#include <winpthreads.h>/* This is our thread function.  It is like main(), but for a thread */void *threadFunc(void *arg){char *str;int i = 0;str = (char*)arg;while(i < 10 ){Sleep(1);printf("threadFunc says: %s\n",str);++i;}return NULL;}int _tmain(int argc, _TCHAR* argv[]){pthread_t pth;// this is our thread identifierint i = 0;/* Create worker thread */pthread_create(&pth,NULL,threadFunc,"processing...");/* wait for our thread to finish before continuing */pthread_join(pth, NULL /* void ** return value could go here */);while(i < 10 ){Sleep(1);printf("main() is running...\n");++i;}return 0;}

運行結果：
