C++多线程（三）事件

事件

解决两个线程通信问题
要注意死锁

g_hEvent = CreateEvent(NULL, FALSE, FALSE, NULL);
WaitForSingleObject(g_hEvent, INFINITE);
ResetEvent(g_hEvent);
SetEvent(g_hEvent);

WaitForMultipleObjects(2, hThread, TRUE, INFINITE);
CloseHandle(g_hEvent);

#include <Windows.h>
#include <stdio.h>
HANDLE g_hEvent = 0;//接收事件句柄
DWORD CALLBACK PrintProc(LPVOID pParam) {
	while (1) {
		WaitForSingleObject(g_hEvent, INFINITE);
		//		ResetEvent( g_hEvent );
		printf("****************\n");
	}
	return 0;
}
DWORD CALLBACK CtrlProc(LPVOID pParam) {
	while (1) {
		Sleep(1000);
		SetEvent(g_hEvent);
	}
	return 0;
}
int main() {
	g_hEvent = CreateEvent(NULL, FALSE, FALSE, NULL);
	DWORD nID = 0;
	HANDLE hThread[2] = { 0 };
	hThread[0] = CreateThread(NULL, 0, PrintProc, NULL, 0, &nID);
	hThread[1] = CreateThread(NULL, 0, CtrlProc, NULL, 0, &nID);
	WaitForMultipleObjects(2, hThread, TRUE, INFINITE);
	CloseHandle(g_hEvent);
	return 0;
