Subject: X Terminal Emulator design question
Summary: How to watch for X Events and traffic on a socket without polling.

I am new to X programming.  I have been reading the O'Reilly books as well
as others.  The concepts of X programming are clear enough based on my
experience with other windowing systems.  I am designing a terminal emulator
and have a design issue I cannot find a good answer for:

How can I code a X event loop that also watches for traffic on a second
socket connection?  I would like to implement the program as a single
process without polling loops.  Is there some way to do it with select()?  I
have already considered these options:
   a second process to watch the socket and signal the main.
   a polling loop to poll the X event queue and the socket.

If anybody knows of a good example of this type of program (terminal emulation)
on the X distribution (R4) other than the standard xterm client, please let
me know.

Thanks.
