DPM_GETPOOLFS(3)

NAME

dpm_getpoolfs - get list of filesystems for a given pool

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

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

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 filesys: tems.
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;
};

This routine returns 0 if the operation was successful or -1 if the operation failed. In the latter case, serrno is set appropriately.

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 Communication error.
