1、主要用到的函数：

　　CreateEvent();

　　ResetEvent();  //将某事件对象设置为非信号状态；

　　SetEvent();  //将某事件对象设置为有信号状态；

 

　　//TRUE代表人工重置的事件对象，当事件有信号时，多有等待的线程都变为可调度线程，可同时运行；最好不要采用人工重置的事件对象；采用自动重置的事件对象，只有一个线

　　//程可调度

　　//FALSE代表非信号状态，最后一个NULL代表匿名的事件对象

　　hEvent = CreateEvent(NULL,TRUE,FALSE,NULL);

 

　　实例代码：

#include <windows.h>
#include <iostream>
#include <stdlib.h>
using namespace std;DWORD WINAPI MyThreadProc1(LPVOID lpParameter);
DWORD WINAPI MyThreadProc2(LPVOID lpParameter);
DWORD WINAPI MyThreadProc3(LPVOID lpParameter);int index = 100;
HANDLE hEvent;int main()
{HANDLE handle1,handle2,handle3;handle1 = CreateThread(NULL,0,MyThreadProc1,NULL,0,NULL);handle2 = CreateThread(NULL,0,MyThreadProc2,NULL,0,NULL);handle3 = CreateThread(NULL,0,MyThreadProc3,NULL,0,NULL);if(NULL == handle1){cout<<"Create Thread failed !"<<endl;return -1;}if(NULL == handle2){cout<<"Create Thread failed !"<<endl;return -1;}if(NULL == handle3){cout<<"Create Thread failed !"<<endl;return -1;}CloseHandle(handle1);CloseHandle(handle2);CloseHandle(handle3);hEvent = CreateEvent(NULL,FALSE,TRUE,NULL);SetEvent(hEvent);Sleep(2000);system("PAUSE");return 0;
}
DWORD WINAPI MyThreadProc1(LPVOID lpParameter)
{while(true){WaitForSingleObject(hEvent,INFINITE);if(index > 0){Sleep(1);cout<<"The Index1 Number is : "<<index--<<endl;}else break;}return 0;
}
DWORD WINAPI MyThreadProc2(LPVOID lpParameter)
{while(true){WaitForSingleObject(hEvent,INFINITE);if(index > 0){Sleep(1);cout<<"The Index2 Number is : "<<index--<<endl;}else break;SetEvent(hEvent);}return 0;
}DWORD WINAPI MyThreadProc3(LPVOID lpParameter)
{while(true){WaitForSingleObject(hEvent,INFINITE);if(index > 0){Sleep(1);cout<<"The Index3 Number is : "<<index--<<endl;}else break;}return 0;
}
