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.

ERRORS

EFAULT: gids or groupnames is a NULL pointer.
EINVAL: nbgroups is not strictly positive or one of the gids does not exist in the internal mapping table.
