初次尝试C++调用WINAPI创建多线程（内容较乱，细心读懂便能初步理解多线程）

// test1.cpp : 定义控制台应用程序的入口点。

//#include "stdafx.h"
//
//
//int main()
//{
//    return 0;
//}

using namespace std;
void sleepdelay(float s);
DWORD WINAPI test_one(LPVOID pM);
DWORD WINAPI test_two(LPVOID pM);

int main()
{
	HANDLE handle_one = CreateThread(NULL, 0, test_one, NULL, 0, NULL);
	//WaitForSingleObject(handle_one, INFINITE);//挂起当前线程，等待线程handle_one返回信号，第二个参数是等待时间最大值，INFNITE是指无限等待；
	CloseHandle(handle_one);
	HANDLE handle_two = CreateThread(NULL, 0, test_two, NULL, 0, NULL);
	WaitForSingleObject(handle_two, INFINITE);

	for (int i = 0; i < 10; i++)
	{
		cout << "main thread!" << endl;
		sleepdelay(0.5);
	}
	return 0;
}

//DWORD WINAPI ThreadFun(LPVOID pM)
//{
//	printf("子线程的线程ID号为:%d\n子线程输出Hello World\n", GetCurrentThreadId());
//	return 0;
//}
////主函数，所谓主函数就是主线程执行的函数
//int main()
//{
//	printf("  最简单的创建多线程实例\n");
//	HANDLE handle = CreateThread(NULL, 0, ThreadFun, NULL, 0, NULL);
//	WaitForSingleObject(handle, INFINITE);
//	return 0;
//}
