Re: 4am, school tomorrow, and these 5 lines of code are killing me!

Crap.  I'm having an episode, here.

Someone answered this for me and I deleted the email.  Now I'm back at
home and I don't remember what it said.

My apologies to the list, but could the person who so graciously answered
this forward me the answer again?

I still can't figure out when to use gchar *some_text[BUFSIZE] and when to
use GString *some_text, and how g_string_sprintf() uses either one of
those.

Thanks,
Derek
