NAME¶

dpm_updatespace - update space

SYNOPSIS¶

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

int dpm_updatespace (char *s_token, u_signed64 req_t_space, u_signed64 req_g_space, time_t req_lifetime, int nbgids, gid_t *req_gids, u_signed64 *actual_t_space, u_signed64 *actual_g_space, time_t *actual_lifetime)

DESCRIPTION¶

dpm_updatespace updates space.

The input arguments are:

s_token

specifies the token returned by a previous reservespace request.

req_t_space

Total space requested in bytes. If set to -1, the current value is unchanged.

req_g_space

Guaranteed space requested in bytes. If set to -1, the current value is unchanged.

req_lifetime

specifies the requested space lifetime (in seconds) relative to the current time. If set to -1, the current value is unchanged.

nbgids

is the size of the array of group ids req_gids. If set to -1, the current value is unchanged.

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.

The output arguments are:

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.

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

s_token is a NULL pointer or nbgids is greater than 0 and req_gids is a NULL pointer.

EINVAL

s_token is invalid (too long) or unknown or the space requested is not a positive value or the number of gids is too big.

SENOSHOST

Host unknown.

SEINTERNAL

Database error.

SECOMERR

Communication error.
