No idea, but you may want to look at some Apache code - that's what it does...
Download source code here:

Basically, you only have to fork() several childs whose "work" is to be blocked on accept().
As all childs are blocked there, when some connection arrives the kernel will awake one of the child processes, so it will go on after accept(), doing its "work".
Some operating systems dont allow blocking on accept(), so the childs are blocked in a file instead.( which, by the way, its more convenient.)
