Threading in Windows using C++

Question

Hi,

In C++ how can you use threads to not block my receive functionality in case of Sockets?

// Receive until the peer closes the connection
do {

    iResult = recv(lhSocket, recvbuf, recvbuflen, 0);
    if ( iResult > 0 )
        printf("Bytes received: %d\n", iResult);
    else if ( iResult == 0 )
        printf("Connection closed\n");
    else
        printf("recv failed: %d\n", WSAGetLastError());

} while( iResult > 0 );

closesocket(lhSocket);
WSACleanup();

Call CreateThread() to create a new thread. If you want to update your UI with information received from the socket, you should define a user message for your window (with a value greater than WM_USER), and call PostMessage() to notify your window of the desired information.
