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.
