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.
SENOSHOST
Host unknown.
SEINTERNAL
Database error.
SECOMERR
Communication error.
