I have brought up a monochrome X server under Amiga Unix (System V
Release 4.0).

I am wondering how a server function [ProcessInputEvents()] is suppose
to register that it wants to be called when the file descriptor it has
open for the mouse and keyboard (one descriptor for both) is ready for
reading.

WaitFor.c looks something like:

	i = select(MAXSOCKS, (int *)LastSelectMask, NULL, NULL, wt);

	selecterr = errno;

	WakeupHandler((unsigned long)i, (pointer)LastSelectMask);

The Wakeuphandler gets called with the number of fd ready and which
fds are ready.  So, in my WakeupHandler() I check FD_ISSET(myfd,
LastSelectMask) to see if myfd (the file descriptor for the
keyboard/mouse device) has input ready and if FD_ISSET() returns TRUE
I call ProcesssInputEvents().  This works.

Is there a better way?  I would think there is a way to bind a file
descriptor to a function so the WaitFor loop would automatically call
ProcessInputEvents() when myfd returned ready from select().
