代码如下：
#include <windows.h>
#include <iostream.h>
DWORD WINAPI Fun1Proc(LPVOID lpParameter);
DWORD WINAPI Fun2Proc(LPVOID lpParameter);
int tickets=100;

void main()
{

hThread1=CreateThread(NULL,0,Fun1Proc,NULL,0,NULL);
hThread2=CreateThread(NULL,0,Fun2Proc,NULL,0,NULL);
CloseHandle(hThread1);
CloseHandle(hThread2);
InitializeCriticalSection(&g_cs);
Sleep(6000);
DeleteCriticalSection(&g_cs);
}
DWORD WINAPI Fun1Proc(LPVOID lpParameter)
{
while(true)
{
EnterCriticalSection(&g_cs);
Sleep(1);
if(tickets>0)
{
Sleep(1);
cout<<"thread1 sell ticket:"<<tickets<<endl;
tickets--;
LeaveCriticalSection(&g_cs);
}
else
{
LeaveCriticalSection(&g_cs);
break;
}
}
return 0;
}
DWORD WINAPI Fun2Proc(LPVOID lpParameter)
{
while(true)
{

}
else
