NAME

       lfc_getgrpbygids - get group names associated with given virtual gids

SYNOPSIS

       #include <sys/types.h>
       #include "lfc_api.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.

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

       ENOMEM	    Memory could not be allocated for unmarshalling the reply.

       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.

       SENOSHOST    Host unknown.

       SENOSSERV    Service unknown.

       SECOMERR     Communication error.

       ENSNACT	    Name server is not running or is being shutdown.

NAME

       dpm_getpools - get list of pools

SYNOPSIS

       #include <sys/types.h>
       #include "dpm_api.h"

       int dpm_getpools (int *nbpools, struct dpm_pool **dpm_pools)

DESCRIPTION

       dpm_getpools gets list of pools.

       The output arguments are:

       nbpools
	      will be set to the number of replies in the array of pools.

       dpm_pools
	      will  be set to the address of an array of dpm_pool structures allocated by the API. The client application is responsible for free-
	      ing the array when not needed anymore. This is also necessary for the gids entry of each dpm_pool.

       struct dpm_pool {
	    char      poolname[CA_MAXPOOLNAMELEN+1];
	    u_signed64	   defsize;
	    int       gc_start_thresh;
	    int       gc_stop_thresh;
	    int       def_lifetime;
	    int       defpintime;
	    int       max_lifetime;
	    int       maxpintime;
	    char      fss_policy[CA_MAXPOLICYLEN+1];
	    char      gc_policy[CA_MAXPOLICYLEN+1];
	    char      mig_policy[CA_MAXPOLICYLEN+1];
	    char      rs_policy[CA_MAXPOLICYLEN+1];
	    int       nbgids
	    gid_t	   *gids;	  /* restrict the pool to given group(s) */
	    char      ret_policy;    /* retention policy: 'R', 'O' or 'C' */
	    char      s_type;	     /* space type: 'V', 'D' or 'P' */
	    u_signed64	   capacity;
	    u_signed64	   free;
	    struct dpm_fs  *elemp;
	    int       nbelem;
	    int       next_elem;     /* next pool element to be used */
       };

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	    nbpools or dpm_pools is a NULL pointer.

       ENOMEM	    Memory could not be allocated for storing the reply.

       SENOSHOST    Host unknown.

       SECOMERR     Communication error.
