关于window线程优先级翻转的问题，我的问题是，线程1为什么不运行？

Question

#include
#include
DWORD WINAPI Fun1Proc(LPVOID lpParameter);
DWORD WINAPI Fun2Proc(LPVOID lpParameter);
DWORD WINAPI Fun3Proc(LPVOID lpParameter);
CRITICAL_SECTION g_cs;
int tickets=15;
void main()
{

HANDLE hThread1;
HANDLE hThread2;
HANDLE hThread3;

hThread1=CreateThread(NULL,0,Fun1Proc,NULL,CREATE_SUSPENDED,NULL);
SetThreadPriority(hThread1,THREAD_PRIORITY_HIGHEST);

SetThreadPriority(hThread2,THREAD_PRIORITY_NORMAL);
hThread3=CreateThread(NULL,0,Fun3Proc,NULL,CREATE_SUSPENDED,NULL);
SetThreadPriority(hThread3,THREAD_PRIORITY_IDLE);

    ResumeThread(hThread1);
    ResumeThread(hThread2);
    ResumeThread(hThread3);
    WaitForSingleObject(hThread1,INFINITE);
//  SetThreadPriority(hThread3,IDLE_PRIORITY_CLASS);

        cout<<"thread1 sell ticket:"<<tickets--<<endl;
    }
    else
        break;

LeaveCriticalSection(&g_cs);

}
return 0;
