【问题描述】:
我正在使用套接字在 Windows 中创建客户端服务器应用程序,如果发生任何问题,我想在运行时从线程抛出异常,但我收到 throw 语句错误。
//create thread in cpp file
CreateThread(NULL,0,startServer,this,0,NULL);
//thread in header file
static unsigned long __stdcall startServer(void *i_SocketTransportServer)
{
((SocketTransportServer*)i_SocketTransportServer)->StartServerThread(((SocketTransportServer *)i_SocketTransportServer)->m_socketServer);
return 0;
}
//and StartServerThread is function called by thread
// SocketTransportServer is inner class of RMLThinTransport
void RMLThinTransport::SocketTransportServer::StartServerThread(SOCKET i_socketServer)
{
m_socketAccept=NULL;
while(true)
{
Sleep(20);
if(m_canAcceptMore)
{
m_canAcceptMore=false;
if(!m_isRunning)
{
break;
}
try
{
m_socketAccept=accept(m_socketServer,NULL,NULL);
if(m_socketAccept==INVALID_SOCKET)
{
int lastError=WSAGetLastError();
closesocket(m_socketAccept);
SocketExceptions
exceptionInAcceptAtServer;
exceptionInAcceptAtServer.detectErrorAccept(&lastError);
throw exceptionInAcceptAtServer;
}
else
{
//_LOG("Client connected",EventTypeInfo) ;
OutputDebugStringW(L"client connected.....");
/* If client connected then setClinetCout value 1 */
setClientCount(1);
m_ClientSockets.push_back(m_socketAccept);
CreateThread(NULL,0,receiveDataAtServer,this,0,NULL);
}
}
catch(SocketExceptions& i_exceptionInAcceptAtServer)
{
/*OutputDebugStringW(L"Can't accept client In Exception. ."); */
throw i_exceptionInAcceptAtServer;//getting runtime error from here
}
}
}
}
现在我想在服务器关闭时抛出错误,但出现运行时错误。那么有什么办法可以让我的主函数出错。对不起,但我是 C++ 新手,所以请帮助我。错误是
