Asyconous socket on Winsock2
Author
i can create CreateSocket( Socket for request connect ) in not useAsynconous
!!BUT when i use Asyconous it error. Error on my server is 10038 (WSAENOTSOCK).!!
what can i do???
int G3DSock::CreateClient(char *IP)
{
sockaddr_in Target;
CSocket = socket( AF_INET, SOCK_STREAM, 0 );
//////This Line////////
WSAAsyncSelect(CSocket, App->m_hWnd, WM_CSOCKET, (FD_CLOSE|FD_READ|FD_CONNECT));
///////////////////////////////
Target.sin_family = AF_INET;
Target.sin_port = htons (5555);
Target.sin_addr.s_addr = inet_addr(IP);
//request to connect
if( connect(CSocket, (sockaddr*)&Target, sizeof(Target)) == SOCKET_ERROR)
{ if (WSAGetLastError()==WSAEWOULDBLOCK)
{ Sleep(750);
connect(CSocket, (LPSOCKADDR)&Target, sizeof(Target) );
return 1;
}
sprintf(App->SockBuffer,"Error: %d",WSAGetLastError() );
MessageBox(App->m_hWnd,App->SockBuffer,"Error", MB_OK);
WSACleanup ();
geEngine_Printf(App->Engine,300,300,"Can not connect");
return 1;
}
return 0;
}
What type of variable is CSocket?
It should be a SOCKET. If not that is your problem caus the
MSDN Library says:
[qoute]
WSAENOTSOCK: The descriptor is not a socket.

Hope this helps,

CSocket is SOCKET. (program work in blocking)
i think WSAEWOULDBLOCK is hapen.
how i can solve it ???

okay, WSAWOULDBLOCK is not *really* an error in this case. Simply
pass over it (set up a catch if statement to ignore it)...
new connect statement...
Once you make the connect() call, you have to wait for a
FD_CONNECT message. Then test for connect errors. (use WSAGETSELECTERROR())
so in short- ignore the WSAWOULDBLOCK error, since it''s simply
telling you that the connect() has blocked the socket from
further activity (until an FD_CONNECT).
