I would use g_spawn_async_with_pipes (see the glib documentation).  It's
more portable than popen (you can't use popen in windows in a
non-console application with some work, which glib does for you) and
will always be there were where GTK is.  Then follow the type of logic
Nix mentioned.

I'm always surprised at what wonderful and elegant functions I find in
the glib routines.  Kudos to the GTK developers for providing this
awesome utility library.  I think it should be considered a standard C
library, especially for things like dynamic strings (way useful for
doing i/o).
