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.

- EINVAL
- The pool is unknown or the length of poolname exceeds CA_MAXPOOLNAMELEN.
- SENOSHOST
