本文通过一个简单示例介绍了如何在Windows环境下使用C语言创建多个线程，并演示了如何使特定线程（本例中为第四个线程）在启动时处于挂起状态，随后再恢复其执行。

一简单实例
比较简单的代码，创建10个线程，其中使第4个线程在一创建就挂起，等到其他的线程执行的差不多的时候再使第4个线程恢复执行。

#include <stdio.h> #include <stdlib.h> #include <windows.h> #define THREAD_NUM 10 DWORD WINAPI PrintThreads (LPVOID); int main () { HANDLE hThread[THREAD_NUM]; DWORD dwThreadID[THREAD_NUM]; for (int i=0; i<THREAD_NUM; ++i) { int isStartImmediate = 0; if(3 == i) isStartImmediate = CREATE_SUSPENDED; hThread[i]=CreateThread(NULL, 0, PrintThreads, (LPVOID)i, isStartImmediate, &dwThreadID[i]); if (hThread[i]) { printf ("Thread launched successfully/n"); } } printf("Start sleep 100, and let other thread excute/n"); Sleep (100); printf("Start sleep 100, and thread 3 excute/n"); ResumeThread(hThread[3]); Sleep(100); for(int i = 0; i<THREAD_NUM; ++i) { if (hThread[i]) { // You need to use this to release kernel objects //when you are done using them. // If a process exits without closing the thread handle, // the operating system drops the reference counts for those objects. // But if a process frequently creates threads without closing the handles, // there could be hundreds of thread kernel objects lying around and these //resource leaks can have a big hit on performance. CloseHandle(hThread[i]); } } return (0); } //function PrintThreads DWORD WINAPI PrintThreads (LPVOID num) { for (int i=0; i<10; i++) printf ("Thread Number is %d%d%d/n", num,num,num); return 0; }
