      [1mdpm_getpools [22mgets 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 neces-
             sary for the gids entry of each dpm_pool.

      This routine returns 0 if the operation was successful  or  -1  if  the
      operation failed. In the latter case, [1mserrno [22mis set appropriately.

      [1mEFAULT       [4m[22mnbpools[24m or [4mdpm_pools[24m is a NULL pointer.

      [1mENOMEM       [22mMemory could not be allocated for storing the reply.

      [1mSENOSHOST    [22mHost unknown.

      [1mSECOMERR     [22mCommunication error.
