    Multithreaded Winsock

    Im working on a program that can send data between a client and a server, kind of like a peer-to-peer chat program.

    I was wondering if anyone can show me a basic layout for a Win32 Multithreaded Winsock program.

    Ive attached the code for my server on this post and my client on the next post, could someone please help point out the errors? The server is extremely laggy, consuming 99% of my CPU (3 GHZ), also the server cannot send data (or the client cannot receive it).

    The client sends fine but doesnt receive data from the server.

    The server code has:

    2 threads (1 for accepting a client, 1 for receiving data from the client)

    The code attached is compilable, so if anyone can try it out and tell me whats wrong? Or post an improved/fixed version of the code.

    Thanx

    The traditional approach is to have your main thread running your servers UI, a worker thread running your accept() calls and passing the I/O socket off to another thread for processing of the connection.
    Wave upon wave of demented avengers march cheerfully out of obscurity unto the dream.

    Im kinda new to the whole multithreading thing, Ive heard that tutorials just cant describe how powerful it is or something, so Is it possible if u could show me just an extremely basic layout to what you just said?

    Some like:

    Code:
    HANDLE hThread1, hThread2;
    
    int Winmain(...)
    {
    	int ThreadId;
    	hThread1 = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)Acceptthread, NULL, 0, (LPDWORD)&ThreadId);
    
    	int ThreadId2;
    	hThread2 = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)IOthread, NULL, 0, (LPDWORD)&ThreadId2);
    }
    
    void Acceptthread()
    {
    }
    
    void IOthread()
    {
    }
    Im not really sure if the code above is right, but I was also wondering, do you need to declare a MUTEX in order to use a thread?

    For powerful windows programming solutions including multithreading, I highly recommend Programming Applications for Microsoft Windows by Jeffrey Richter.

    get a job, or better yet, look at your community library or a university library, they are sure to have computer programming books at them.
