写爬虫的时候发现单线程太慢，研究了一下多线程写法

// testThread.cpp : 定义控制台应用程序的入口点。

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

#define MAX_THREADS 3

//子线程函数  
DWORD WINAPI ThreadFun(LPVOID pM)  
{  
    printf("n我是子线程：%dn",pM);
    printf("子线程的线程ID号为：%dn", GetCurrentThreadId());  
    return 0;  
} 
int _tmain(int argc, _TCHAR* argv[])
{
    printf("我是主线程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);  //创建多线程
    }
    if(hThread[i]==NULL)
    {
        ExitProcess(i);//退出进程
    }else{
        printf("hThread:,%dn",hThread[i]);
    }
    WaitForMultipleObjects(MAX_THREADS,hThread,TRUE,INFINITE);//主线程等待子线程结束

    for(i = 0; i < MAX_THREADS; i++){
         CloseHandle(hThread[i]);//关闭线程
    }

    return 0;
}
