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;
int weight;
};
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
- Communication error.
