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.

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.

- EINVAL
-
nbtokens is not strictly positive or the specified tokens are invalid/unknown.
- SENOSHOST
-
Host unknown.
- SEINTERNAL
