SYNOPSIS
       #include <sys/types.h>

       int lfc_getgrpbygids (int nbgroups, gid_t *gids, char **groupnames)

DESCRIPTION
       lfc_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.
