多线程编程

编写的多线程程序，是根据孙鑫的视频讲解写的，这个代码重点在于线程同步，需要注意的是线程的时间片的划分，如果主线程的时间片一直在运行的话，程序是不会进入子线程的。

// MultiThread.cpp : 定义控制台应用程序的入口点。

#include "stdafx.h"
#include<windows.h>
#include<iostream>
using namespace std;
DWORD WINAPI Thread1(LPVOID lpParamenter);
DWORD WINAPI Thread2(LPVOID lpParamenter);
int ticket = 100;
HANDLE hMutex;
int main(int argc, _TCHAR* argv[])
{
    HANDLE hThread1, hThread2;
    hThread1 = CreateThread(NULL, 0, Thread1, NULL, 0, NULL);
    hThread2 = CreateThread(NULL, 0, Thread2, NULL, 0, NULL);
    CloseHandle(hThread1);
    CloseHandle(hThread2);
    hMutex=CreateMutex(NULL,false,NULL);
    Sleep(1000);
    return 0;
}

DWORD WINAPI Thread1(LPVOID lpParamenter)
{
    while (true)
    {
        WaitForSingleObject(hMutex, INFINITE);
        if (ticket > 0)
        {
            Sleep(1);
            cout << "Thread1 sell ticket:" << ticket-- << endl;

        }
        else
        {
            break;
        }
        ReleaseMutex(hMutex);
    }
    return 0;
}

DWORD WINAPI Thread2(LPVOID lpParamenter)
{
    while (true)
    {
        WaitForSingleObject(hMutex, INFINITE);
        if (ticket > 0)
        {
            Sleep(1);
            cout << "Thread2 sell ticket:" << ticket-- << endl;

        }
        else
        {
            break;
        }
        ReleaseMutex(hMutex);
    }
    return 0;
}
