So do I have a memory leak then?  What is the proper way around this?
Do I have to remember to delete all the strings myself after calling
the gtk_clist_clear() function.  Or can I delete them after adding
them to the clist?  I thought I tried using the same string with
different values each time I added them to the clist and I ended up
with all the entries being the same as the last one I had set the
string to.

e.g,

sprintf(str, "a");
// add to clist
sprintf(str, "b");
// add to clist

and both entries would be b.

So I assumed the clist just had a pointer that it would free when the
list is cleared.
