It still outputs an error message if there is no data received by the function it is outputing. "trdp_pdcom.c:972 PDframe size error (8))". I feel that if WSARecvMsg is returning SOCKET_ERROR then numBytes will not be a valid value for our case. So I suggest returning -1 if there is SOCKET_ERROR. Could you please review if my suggestion will work? else { pMessage->dwFlags = flags; res = WSARecvMsg(sock, pMessage, &numBytes, NULL, NULL); if (0 != res) { DWORD err = WSAGetLastError(); if (err != WSAEWOULDBLOCK)...
