Send/Recv Error

I''m trying to write a winsock wrapper, and I''m good so far up to my send and receive class functions. I''m trying to be able to send any type of data I can via these functions. Here is the code: int CNetwork::Send(void *buffer, int bufLen) { char *data = NULL; data = new char[bufLen]; memcpy(data, buffer, bufLen); if (send(socketInfo, data, bufLen, NULL) != 0) { if (debug == true) ProcessError(WSAGetLastError()); return 1; } else return 0; } int CNetwork::Receive(void *buffer, int bufLen) { char *data = NULL; data = new char[bufLen]; if (recv(socketInfo, data, bufLen, NULL) != 0) { if (debug == true) ProcessError(WSAGetLastError()); return 1; } else { memcpy(data, buffer, sizeof(data)); return 0; } } The send function returns a WSAENOTCONN error (Socket is not connected). This is when sending for the first time from the host to the client. However, socketInfo does contain data and passed without error through the bind, listen, and accept process. My code probably sucks though. Any suggestions would be appreciated. Thanks for all your help.

Just to be clear, recv(...) returns the amount of data read or an error. So, you will use this return value if it''s not an errror (I guess that if it is > 0). Look in socket docs....
