C語言 多線程測試

1、CreateThread 在主線程的基礎上創建一個新線程

2、WaitForMultipleObjects 主線程等待子線程

3、CloseHandle 關閉線程

// testThread.cpp : 定義控制台應用程序的入口點。

#include "stdafx.h"
#include "windows.h"

#define MAX_THREADS 3

//子線程函數  
DWORD WINAPI ThreadFun(LPVOID pM)  
{  
    printf("\n我是子線程：%d\n",pM);
    printf("子線程的線程ID號為：%d\n", GetCurrentThreadId());  
    return 0;  
} 

int _tmain(int argc, _TCHAR* argv[])
{
    printf("我是主線程\n");

    //HANDLE handle = CreateThread(NULL, 0, ThreadFun, NULL, 0, NULL);  
    //WaitForSingleObject(handle, INFINITE);     

    HANDLE hThread[MAX_THREADS];
    int i;
    for(i = 0; i < MAX_THREADS; i++){
        hThread[i] = CreateThread(NULL, 0, ThreadFun,(LPVOID *) i, 0, NULL);  //創建多線程
    }
    if(hThread[i]==NULL)
    {
        ExitProcess(i);//退出進程
    }else{
        printf("hThread:,%d\n",hThread[i]);
    }

    WaitForMultipleObjects(MAX_THREADS,hThread,TRUE,INFINITE);//主線程等待子線程結束

    for(i = 0; i < MAX_THREADS; i++){
         CloseHandle(hThread[i]);//關閉線程
    }

    return 0;
}

 測試結果如下：
