This routine compares the data at arg1ptr with that at arg2ptr using the
sort compare code in khPtr->sortCmpCode.
Use this function when you need to compare foreign key values with key values returned, especially for SORT_NLS, when strcmp() won't perform the job needed.
Return: less than 0 if *arg1ptr < *arg2ptr; 0 if equal; greater
than 0 if *arg1ptr > *arg2ptr.
