Parameter passing advice...

[Chris Elston <celston corky sapien net>]

A common "problem" when working the C version of GTK is the what's and
how's of passing parameters to signal handling functions.  If I'm not mistaken,
every "signal_connect" function ends in a gpointer (* void) parameter
which is there for the programmer to use for his own purpose(s).  Now,
I have experience with C but I'm no expert so this next question is both
related to that and my curiousity with GTK.

Sometimes, one parameter is not enough.  What methods have you all used in
the past to get around having only one gpointer at your disposal when you
need much more?  GLists?  Arrays?  some kind of hack around with regards
to the nature of void pointers?
