       dpm_getpools - get list of pools


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

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


       dpm_getpools gets list of pools.

       The output arguments are:

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

              will  be  set  to the address of an array of dpm_pool structures
              allocated by the API. The client application is responsible  for
              freeing  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       defpintime;
            int       max_lifetime;
            int       maxpintime;

            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’ */

       This routine returns 0 if the operation was successful  or  -1  if  the
       operation failed. In the latter case, serrno is set appropriately.


       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.
