I wish to write a software which uses both X Windows (in C language) and
Common Lisp. The core part of the program is written in Common-Lisp and
the windowing interface will be written in X using C. Now my question is
that I wish to have the common lisp running in one of my windows that I
create in my application and all I/O such as callbacks and keyboard
input should be passed to some common lisp functions and the output from
Common Lisp should occur in my window (window 3 .. see below).
Something like :

----------------------- |

-------------------------------
The above shows an X Window which consists of (1) an Xlib window to show
graphics, (2) X Toolkit button box where the callback are passed to the
CommonLisp and (3) and any X window where the I/O goes to the underlying
Common-Lisp.
In this case, I should be able to type Lisp command in window no. (3)
and the underlying Common-lisp should interpret that as input and
execute that lisp code. I am unsure of how to implement the Common Lisp
in an X window to handle this. If you think I am being unclear, send me
a note and I'll give more info. Any help would be very much
appreciated. Thanks in advance.

It provides facilities at the same level as Xlib. CLX is included in the X11R2 distribution. Unfortunately, it isn't well documented. >In this case, I should be able to type Lisp command in window no.

Xterm takes an argument, -e, that lets you specify a command to run with its I/O directed to the window that is created.
