Re: Combo question

[Wallace Owen <wallace owen L-3Com com>]

You need to allocate storage to hold the strings pointed at by the 2nd
parm to g_list_append().  The glist isn't responsible for allocating
fresh string space to hold the various strings pointed at by that 2nd
parm, so if you keep using the same pointer in calls to g_list_append(),
and at the end all those same pointers point to 'Zack', that's what you
should expect to see in the list.

Your eyes are weary from staring at the CRT.  You feel sleepy.  Notice
how restful it is to watch the cursor blink.  Close your eyes.  The   
opinions stated above are yours.  You cannot imagine why you ever felt
otherwise.
