Declared in: TCPSocketAsync.h |
virtual int Send( const char* pBuffer, unsigned long ulBufferLength);
Send data over the sockets Send may fail because the system isn't ready to send the data, check out the value of the send SOCKET_ERROR - Failure 0 - Send couldn't finish because it would block if there was a blocking buffer, it was queued (check out AllowBlockedBuffer in CAsyncSocket) Value - Bytes sent
try { //Send the data int iResult; iResult=SendNoAdd(pBuffer, ulBufferLength); //Did we succeed ? if (iResult==GetErrorCode()) //Is it blocked send ? if (WSAGetLastError()==WSAEWOULDBLOCK && GetBlockedBuffer()) { //Add to the buffer, if we have one GetBlockedBuffer()->AddRecord(CBlockedBuffer::CBlockedData(pBuffer, ulBufferLength)); //We have not error iResult=0; } //Blocking error (not really an error) else if (WSAGetLastError()==WSAEWOULDBLOCK) return 0; else //Set the error code SetLastError("Send"); //Done return iResult; } ERROR_HANDLER_RETURN("Send",GetErrorCode())
