Retrieves the tag/reference number pairs of the HDF objects belonging to a vgroup.
Return value
Returns the number of tag/reference number pairs obtained from a vgroup if successful and FAIL (or -1) otherwise.
Description
Vgettagrefs retrieves at most num_of_pairs number of tag/reference number pairs belonging to the vgroup, vgroup_id, and stores them in the buffers tag_array and ref_array.
The input parameter num_of_pairs specifies the maximum number of tag/reference number pairs to be returned. The size of the arrays, tag_array and ref_array, must be at least num_of_pairs.
