CAsyncSocket::OnConnect

virtual void OnConnect( int nErrorCode );

Parameters

nErrorCode

The most recent error on a socket. The following error codes apply to the OnConnect member function:

0 The function executed successfully.
WSAEADDRINUSE The specified address is already in use.
WSAEADDRNOTAVAIL The specified address is not available from the local machine.
WSAEAFNOSUPPORT Addresses in the specified family cannot be used with this socket.
WSAECONNREFUSED The attempt to connect was forcefully rejected.
WSAEDESTADDRREQ A destination address is required.
WSAEFAULT The lpSockAddrLen argument is incorrect.
WSAEINVAL The socket is already bound to an address.
WSAEISCONN The socket is already connected.
WSAEMFILE No more file descriptors are available.
WSAENETUNREACH The network cannot be reached from this host at this time.
WSAENOBUFS No buffer space is available. The socket cannot be connected.
WSAENOTCONN The socket is not connected.
WSAENOTSOCK The descriptor is a file, not a socket.
WSAETIMEDOUT The attempt to connect timed out without establishing a connection.

Remarks

Called by the framework to notify this connecting socket that its connection attempt is completed, whether successfully or in error.

Important In CSocket, the OnConnect notification function is never called.

For connections, you simply call Connect, which will return when the connection is completed (either successfully or in error). How connection notifications are handled is an MFC implementation detail.

For more information, see the article Windows Sockets: Socket Notifications in Visual C++ Programmer's Guide.
