NAME

       dpm_reservespace - reserve space

SYNOPSIS

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

       int dpm_reservespace (const char s_type, const char *u_token, const char ret_policy, const
       char ac_latency, u_signed64 req_t_space, u_signed64 req_g_space, time_t req_lifetime,  int
       nbgids,   gid_t   *req_gids,   const   char  *poolname,  char  *actual_s_type,  u_signed64
       *actual_t_space, u_signed64 *actual_g_space, time_t *actual_lifetime, char *s_token)

DESCRIPTION

       dpm_reservespace reserves space.

       The input arguments are:

       s_type specifies the type of space requested. It can be V (for Volatile), D (for Durable),
              P (for Permanent) or - (for any).

       u_token
              specifies the user provided description associated with the request.  This argument
              may be NULL.

       ret_policy
              specifies the retention policy requested. It can be R (for REPLICA), O (for OUTPUT)
              or C (for CUSTODIAL).

       ac_latency
              specifies  the  access  latency  requested.  It  can  be  O  (for ONLINE) or N (for
              NEARLINE).

       req_t_space
              Total space requested in bytes.

       req_g_space
              Guaranteed space requested in bytes.

       req_lifetime
              specifies the requested space lifetime (in seconds) relative to the current time.

       nbgids is the size of the array of group ids req_gids.

       req_gids
              when zero, the space is reserved for the user if the requester has a proxy  without
              VOMS  extension  or for the group if the requester has a proxy with VOMS extension.
              If not zero, the space is reserved for this set of group ids.  If the  caller  does
              not belong to the group, it must have ADMIN privileges.

       poolname
              If not NULL, reserves the space in that disk pool.

       The output arguments are:

       actual_s_type
              Type of reserved space.

       actual_t_space
              Total space reserved in bytes (best effort).

       actual_g_space
              Guaranteed space reserved in bytes.

       actual_lifetime
              Lifetime of the reserved space (in seconds) relative to the current time.

       s_token
              Address of a buffer to receive the system allocated token.

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

       EACCES       The caller does not belong to the group identified by req_gid  and  does  not
                    have ADMIN privileges.

       EFAULT       nbgids is greater than 0 and req_gids is a NULL pointer.

       EINVAL       The  space  type is invalid or the length of the user space token description
                    is greater than 255, the space requested is not a positive  value,  the  pool
                    name is longer than CA_MAXPOOLNAMELEN or unknown or the number of gids is too
                    big.

       SENOSHOST    Host unknown.

       SEINTERNAL   Database error.

       SECOMERR     Communication error.
