DPM_GETSPACEMD(3)
NAME
dpm_getspacemd - get space metadata
SYNOPSIS
#include <sys/types.h> #include "dpm_api.h" int dpm_getspacemd (int nbtokens, char **s_tokens, int *nbreplies, struct dpm_space_metadata **spacemd)
DESCRIPTION
dpm_getspacemd gets space metadata.
The input arguments are:
- nbtokens
- specifies the number of tokens in the request.
- s_tokens
- specifies an array of tokens returned by previous reservespace requests.
- The output arguments are:
- nbreplies
- will be set to the number of replies in the array of space metadata.
- spacemd
- will be set to the address of an array of dpm_space_metadata structures allocated by the API. The client application is responsible for freeing the array when not needed anymore.
- struct dpm_space_metadata {
- char s_type;
char s_token[CA_MAXDPMTOKENLEN+1];
uid_t s_uid;
gid_t s_gid;
char ret_policy;
char ac_latency;
char u_token[256];
char client_dn[256];
u_signed64 t_space; /* Total space */
u_signed64 g_space; /* Guaranteed space */
signed64 u_space; /* Unused space */
char poolname[CA_MAXPOOLNAMELEN+1];
time_t a_lifetime; /* Lifetime assigned */
time_t r_lifetime; /* Remaining lifetime */
int nbgids;
gid_t *gids; /* restrict the space to given group(s) */ - };
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_tokens , nbreplies or spacemd is a NULL pointer.
ENOMEM Memory could not be allocated for storing the reply.
- EINVAL nbtokens is not strictly positive or the specified tokens
- are invalid/unknown.
- SENOSHOST Host unknown.
- SEINTERNAL Database error.
- SECOMERR Communication error.
