This works for me:

XmListWidget	List1;
register int	n;
Arg			args[MAX_ARGS];
XmStringTable	ItemTab;
int			count;

    n = 0;
    XtSetArg(args[n], XmNitems, &ItemTab); n++;
    XtSetArg(args[n], XmNitemCount, &count); n++;
    XtGetValues(List1, args, n);


Now you can pull the items out of ItemTab and manipulate them however you
like.  Just don't free these strings or the table.  For example:

for (n = 0; n < count; n++)
	if (XmStringCompare(ItemTab[n], teststr)
	   {
		result = XmStringGetLtoR(ItemTab[n], XmSTRING_DEFAULT_CHARSET, &str);
      
	     if (result) 
		   {
			  printf("Found: %s\n", str);
			}
	      else
		{
		  printf ("Couldn't get string for n = %d\n", n);
		}
	    }

Hope this helps.  If you have any more questions, please ask.
