NAME

dpm_getpoolfs - get list of filesystems for a given pool

SYNOPSIS

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

int dpm_getpoolfs (char *poolname, int *nbfs, struct dpm_fs **dpm_fs)

DESCRIPTION

dpm_getpoolfs gets list of filesystems for a given pool.

The input argument is:

poolname
specifies the disk pool name previously defined using dpm_addpool.

The output arguments are:

nbfs
will be set to the number of replies in the array of filesystems.
dpm_fs
will be set to the address of an array of dpm_fs structures allocated by the API. The client application is responsible for freeing the array when not needed anymore.
 struct dpm_fs {
         char            poolname[CA_MAXPOOLNAMELEN+1];
         char            server[CA_MAXHOSTNAMELEN+1];
         char            fs[80];
         u_signed64      capacity;
         u_signed64      free;
         int             status;
 };

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
poolname, nbfs or dpm_fs is a NULL pointer.
ENOMEM
Memory could not be allocated for storing the reply.
EINVAL
The pool is unknown or the length of poolname exceeds CA_MAXPOOLNAMELEN.
SENOSHOST
Host unknown.
SECOMERR
