NAME

       hdf_sort_obj  - sort the children of an HDF node

SYNOPSIS

       #include <util/neo_hdf.h>

       hdf_sort_obj()

ARGUMENTS

       h - HDF node
       compareFunc - function which returns 1,0,-1 depending on some
       criteria.  The arguments to this sort function
       are pointers to pointers to HDF elements.  For
       example:
       int sortByName(const void *a, const void *b) {
       HDF **ha = (HDF **)a;
       HDF **hb = (HDF **)b;
       *
       return strcasecmp(hdf_obj_name(*ha), hdf_obj_name(*hb));
       }
       *

DESCRIPTION

       hdf_sort_obj  will  sort  the  children  of  an  HDF  node,  based on the given comparison
       function.  This function works by creating an array of the pointers for each child  object
       of  h, using qsort to sort that array, and then re-ordering the linked list of children to
       the new order.  The qsort compare function uses a pointer to the value in the array, which
       in  our case is a pointer to an HDF struct, so your comparison function should work on HDF
       ** pointers.

RETURN VALUE

       None (h children will be sorted)
