在多線程的程序里，不同的線程可以做不同的事情，下面演示一個多線程的例子。

// MultiThread.cpp : 定義控制臺應用程序的入口點。
//

#include "stbdafx.h"
#include <windows.h>
#include <iostream>

using namespace std;
int tickets = 100;
HANDLE hMutex;

DWORD WINAPI Fun1Proc(LPVOID lp);
DWORD WINAPI Fun2Proc(LPVOID lp);

int _tmain(int argc, _TCHAR* argv[])
{
HANDLE hThread1,hThread2;
hThread1 = CreateThread(NULL,0,Fun1Proc,NULL,0,NULL);
hThread2 = CreateThread(NULL,0,Fun2Proc,NULL,0,NULL);
CloseHandle(hThread1);
CloseHandle(hThread2);
hMutex = CreateMutex(NULL,FALSE,NULL);

Sleep(2000);
system("pause");
return 0;
}

DWORD WINAPI Fun1Proc(LPVOID lp)
{
while(1)
{
　WaitForSingleObject(hMutex,INFINITE);
　if(tickets > 0)
　{
　Sleep(10);
　cout << "thread1 sell ticket." << tickets-- <<endl;
　}
　else
　break;
　ReleaseMutex(hMutex);
}
return 0;
}

DWORD WINAPI Fun2Proc(LPVOID lp)
{
while(1)
{
　WaitForSingleObject(hMutex,INFINITE);
　if(tickets > 0)
　cout << "thread2 sell ticket." << tickets-- <<endl;
　else
　break;
　ReleaseMutex(hMutex);
}
return 0;
}
