LGRP_PARENTS(3LGRP)					   LGRP_PARENTS(3LGRP)

NAME
       lgrp_parents - get parents of given lgroup

SYNOPSIS
       cc [ flag ... ] file... -llgrp [ library ... ]
       #include <sys/lgrp_user.h>

       int lgrp_parents(lgrp_cookie_t cookie, lgrp_id_t child,
	    lgrp_id_t *lgrp_array, uint_t lgrp_array_size);

DESCRIPTION
       The  lgrp_parents()  function takes a cookie representing a snapshot of
       the lgroup hierarchy obtained from  lgrp_init(3LGRP)  and  returns  the
       number of parent lgroups of the specified lgroup. If lgrp_array is non-
       null and the lgrp_array_size is non-zero, the array is filled  with  as
       many  of the parent lgroup IDs as will fit given the size of the array.
       For the root lgroup, the number	of  parents  returned  is  0  and  the
       lgrp_array argument is not filled in.

RETURN VALUES
       Upon successful completion, lgrp_parents() returns the number of parent
       lgroup IDs. Otherwise, −1 is returned and errno is set to indicate  the
       error.

ERRORS
       The lgrp_parents() function will fail if:

       EINVAL
		 The specified cookie or lgroup ID is not valid.

       ESRCH
		 The specified lgroup ID was not found.
