WSAWaitForMultipleEvents函数第二次调用报错

Question

//接受远程连接的线程
UINT WINAPI AcceptThread(PVOID pParam)

for(;;)
{
DWORD EventCaused = WSAWaitForMultipleEvents(
2,
hEvnets,  
FALSE,                  
WSA_INFINITE, 
FALSE); if(EventCaused == WSA_WAIT_FAILED || EventCaused == WAIT_OBJECT_0)

} }

}

return 0;
}进入循环后，第二次WSAWaitForMultipleEvents函数报错，不知道为什么？
