      [1mint dpm_addpool (struct dpm_pool *[4m[22mdpm_pool[24m[1m)[0m

[1mDESCRIPTION[0m
      [1mdpm_addpool [22mdefines a new disk pool.

      [4mdpm_pool[0m
             contains the pool definition.

      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;
           char      ret_policy;
           char      s_type;
           u_signed64     capacity;
           u_signed64     free;
           int       nbelem;
      };

      [4mpoolname[0m
             specifies the disk pool name.

      [4mdefsize[0m
             specifies  the  default  amount of space reserved for a file (in
             bytes).

      [4mgc_start_thresh[0m
             specifies the minimum free space in the pool.  If the percentage
             of  free  space  goes below this value, the garbage collector is
             started. Default is 0.

      [4mgc_stop_thresh[0m
             specifies the percentage of free space in the pool  above  which
             the garbage collector is stopped. Default is 0.

      [4mdef_lifetime[0m
             specifies  the  default time a space or volatile file is kept in
             the system (in seconds).

      [4mdefpintime[0m
             specifies the default time a file is kept on a  given  disk  (in
             seconds).

      [4mmax_lifetime[0m
             specifies  the  maximum time a space or volatile file is kept in
             the system (in seconds).

      [4mmaxpintime[0m
             specifies the maximum time a file is kept on a  given  disk  (in
             seconds).

      [4mnbgids[24m is the size of the array of group ids [4mgids[24m.

      [4mgids[24m   The disk pool is restricted to this set of gids unless the group
             gid is zero.

      [4mret_policy[0m
             specifies the retention policy supported by the  disk  pool.  It
             can be [1mR [22m(for Replica), [1mO [22m(for Output) or [1mC [22m(for Custodial).

      [4ms_type[24m indicates  the  type of space supported in the disk pool. It can
             be [1mV [22m(for Volatile), [1mD [22m(for Durable), [1mP [22m(for Permanent) or [1m- [22m(to
             accept any type).

      This function requires ADMIN privilege.

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

[1mERRORS[0m
      [1mEACCES       [22mThe caller does not have ADMIN privilege.

      [1mEFAULT       [4m[22mdpm_pool[24m is a NULL pointer.

      [1mEEXIST       [22mThis pool exists already.

      [1mENOMEM       [22mMemory could not be allocated for storing the pool defini-
                   tion.

      [1mEINVAL       [22mThe  length  of  [4mpoolname[24m exceeds [1mCA_MAXPOOLNAMELEN [22mor the
                   number of gids is too big.

      [1mSENOSHOST    [22mHost unknown.

      [1mSEINTERNAL   [22mDatabase error.

      [1mSECOMERR     [22mCommunication error.
