.SH NAME
dpm_getspacemd \- get space metadata
.SH SYNOPSIS
.B #include <sys/types.h>
.br
\fB#include "dpm_api.h"\fR
.sp
.BI "int dpm_getspacemd (int " nbtokens ,
.BI "char **" s_tokens ,
.BI "int *" nbreplies ,
.BI "struct dpm_space_metadata **" spacemd )
.SH DESCRIPTION
.B dpm_getspacemd
gets space metadata.
.LP
The input arguments are:
.TP
.I nbtokens
specifies the number of tokens in the request.
.TP
.I s_tokens
specifies an array of tokens returned by previous reservespace requests.
.LP
The output arguments are:
.TP
.I nbreplies
will be set to the number of replies in the array of space metadata.
.TP
.I 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.

is not strictly positive or the specified tokens are invalid/unknown.
.TP
