dpns_getgrpbygids - get group names associated with given virtual gids
SYNOPSIS
#include <sys/types.h>
#include "dpns_api.h"
int dpns_getgrpbygids (int nbgroups, gid_t *gids, char **groupnames)
DESCRIPTION
dpns_getgrpbygids gets the group names associated with given virtual
gids.
nbgroups
specifies the number of gids.
gids specifies the Virtual Group Ids.
groupnames
specifies a buffer to receive the pointers to the associated
group names. The buffer must be big enough to hold nbgroups
pointer values. The client application is responsible for
freeing the array elements when not needed anymore.
RETURN VALUE
This routine returns 0 if the operation was successful or -1 if the
operation failed. In the latter case, serrno is set appropriately.

not exist in the internal mapping table.
