hdf_sort_obj(3) util/neo_hdf.h hdf_sort_obj(3) 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 com- parison 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-or- dering 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.
