互斥对象 出现的错误
代码：
hMutex = CreateMutex(NULL,FALSE,NULL);
DWORD WINAPI ThreadProc1(
LPVOID lpParameter
)
{
while (1)
{
WaitForSingleObject(hMutex,INFINITE);
if (tickets > 0)
{
printf_s("Thread1 sells ticket :%d\n",tickets--);
printf_s("Thread1 sells ticket \n");
}
else
break;
ReleaseMutex(hMutex);
}
return 0;
}
DWORD WINAPI ThreadProc2(
LPVOID lpParameter
)
{
while (1)
{
WaitForSingleObject(hMutex,INFINITE);
if (tickets > 0)
{
printf_s("Thread2 sells ticket :%d\n",tickets--);
}
else
break;
ReleaseMutex(hMutex);
}
return 0;
}
利用互斥对象实际应该是先输出线程1的两句话，再输出线程2，但有时候最开始的输出时如下面图片所示，线程1与线程2交替输出，有点搞不懂
