Interaction with a daemon in C ++ with sockets

Question

I am writing a daemon that should work both in the background and take care of tasks, as well as receive input directly from the interface. I am trying to use sockets to take care of this task, however I cannot get it to work correctly, as the sockets pause the program while waiting for the connection. Is there any way around this?

I use shell wrappers provided at http://linuxgazette.net/issue74/tougher.html

Thanks for any help.

while (!done)

        // Loop over each event source or internal worker
        for each module

            if (module.hasWorkDoTo())
            {
                // Generally, do as little work as possible; e.g. process a single event for this module.
                // But tinker with this to manage priorities if need be.
                // E.g. Maybe allow the GUI to flush its queue.
                module.doSomeWork();
                workDone = true;
            }
        }
        if (!workDone)
        {
            // System idle. No Sleep for a bit so we have benign idle baheviour.
            nanosleep(...);
        }
