If field 1 is identical, then fall through to field 2.  If field 2 is 
identical, then fall through to field 3.  And so on, for all the fields 
you want to sort on.  The value you return from the comparison function 
tells whether the first ENTRY structure is less than, equal, or greater 
than the second ENTRY structure.
