    Question controlling one program from another

    I have two (GUI context) apps that perform seperate functions and get used independently, but also relate -- or i'd like them to. Basically, one would be sending user level commands to the other while both are running. Where should I start my investigation? I only need a few options and short lines of text exchanged, so should I just use signals and a fifo? Or can I use sockets (which I've never done before...)
    C programming resources:
    GNU C Function and Macro Index -- glibc reference manual
    The C Book -- nice online learner guide
    Current ISO draft standard
    CCAN -- new CPAN like open source library repository
    3 (different) GNU debugger tutorials: #1 -- #2 -- #3
    cpwiki -- our wiki on sourceforge

    You could use sockets, I believe.
    You could also use SendMessage.

    I can't think of any other right now. :-/

    There is also possibility of named-pipes or memory mapped file...
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.
