Message passing

[kmachstang]

Hello,

I think I am misunderstanding something which is leading to some confusion.

I am using fork to have a concurrent TCP listening server on a linux machine.

The Client program uses select() for I/O multiplexing.

When the clients connect, i have a shared memory segment where on connection i save the return value of the accept function ( I assumed this was the connection id ).

I then have a function that allows one client to send a message to another client where i use the send function. Currently, the message is just echo'd back to the client that sends the message.

I don't think I am understanding this right, could someone explain how I might relay a message from one client to another, through the server, over TCP???

Thanks,
Kyle
