Get list of filesystems for a given pool

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 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;
};
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.
