You can do this easily by getting the file descriptor of the display
connection, and adding that to your select() call.  E.g.:

	Display * dpy;
	int readfs, xfd;
	...
	xfd = ConnectionNumber(dpy);
	readfds |= 1 << xfd;
	...
	select( ..., &readfds, ... );
	...
	if ( readfds & (1 << xfd) )
		ProcessXEvents(dpy);
