Re: Sockets question

Hi,

I have a server that it very simple. I declare a socket and I get a
descriptor and when calling listen i pass the value 5
(listen(g_socketDescriptor, 5) so I can queue 5 connections on that
socket.

Every time the blocking call to Accept() returns, I get back a new
descriptor say x1 ,x2,... x5
and I spawn a thread that does some heavy processing and write back to
the socket descriptor (x1,..,x5) that the thread was spawned with then
after a bit, it writes to this socket.

on the client side I noticed sometimes corrupted data which means the
threads when they write to those descriptors (using the call send()) i
might be sending data to the wrong client.

My understanding is that the descriptor is a unique identifier that i
could use to decide who to exactly send the data too from the
server...

Can anyone see what is going wrong here? The code is too big so I`ll
just maybe give a snapshot.

        g_socketDescriptor = socket(PF_INET,SOCK_STREAM,0);
        bind(g_socketDescriptor,(struct sockaddr*)&socketAddress,
sizeof (socketAddress)
        listen(g_socketDescriptor,5)

        int finalId;
        pthread_t tid;
        while (true)
        {
            if ((finalId = accept(g_socketDescriptor,
                                (struct sockaddr*)&remoteAddress,
                                &remoteAddressLen)) == -1)
            {
                SpawnNewThreadHere(finalId);
            }
       }

Thread code:

MainThread(finalId)
{
    // do some processing, then send some data
    send(finalId,SomeBuffer);}

~Thread()
{
    close(finalId);

}

Thanks.
