windows線程創建與線程處理函數

近期工作中用到了Windows中的線程創建函數，實例代碼如下：

#include <QCoreApplication>

#include <windows.h>

#include <iostream>

#include <windef.h>

using namespace std;

//聲明瞭兩個線程處理函數

DWORD WINAPI Fun1Proc(LPVOID lpParameter);

DWORD WINAPI Fun2Proc(LPVOID lpParameter);

//公有變量作爲共享資源

int tickets=100;

//互斥鎖句柄

HANDLE hMutex;

int main(int argc, char *argv[])

{

    QCoreApplication a(argc, argv);

    HANDLE hThread1;

    HANDLE hThread2;

    //創建互斥鎖

    hMutex=CreateMutex(NULL,FALSE,NULL);

    //使用CreateThread函數創建線程hThread1和hThread2

    hThread1=CreateThread(NULL,0,(LPTHREAD_START_ROUTINE)Fun1Proc,NULL,0,NULL);

    hThread2=CreateThread(NULL,0,Fun2Proc,NULL,0,NULL);

    while(true)

    {

        //主線程在互斥鎖中出售火車票

        WaitForSingleObject(hMutex,INFINITE);

        if(tickets>0)

            cout<<"main thread sell ticket:"<<tickets--<<endl;

        else

            break;

        ReleaseMutex(hMutex);

    }

    return 0;

    //銷售完火車票後關閉兩個子線程

    CloseHandle(hThread1);

    CloseHandle(hThread2);

    Sleep(4000);

    return a.exec();

}

//線程hThread1的線程處理函數

DWORD WINAPI Fun1Proc(LPVOID lpParameter)

{

    while(true)

    {

        WaitForSingleObject(hMutex,INFINITE);

        if(tickets>0)

            cout<<"thread1 sell ticket:"<<tickets--<<endl;

        else

            break;

        ReleaseMutex(hMutex);

    }

    return 0;

}

//線程hThread2的線程處理函數

DWORD WINAPI Fun2Proc(LPVOID lpParameter)

{

    while(true)

    {

        WaitForSingleObject(hMutex,INFINITE);

        if(tickets>0)

            cout<<"thread2 sell ticket:"<<tickets--<<endl;

        else

            break;

        ReleaseMutex(hMutex);

    }

    return 0;

}
