LGRP_RESOURCES(3LGRP)					 LGRP_RESOURCES(3LGRP)

NAME
       lgrp_resources - get lgroup resources of given lgroup

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

       int lgrp_resources(lgrp_cookie_t cookie, lgrp_id_t lgrp,
	    lgrp_id_t *lgrpids, uint_t count, lgrp_rsrc_t type);

DESCRIPTION
       The lgrp_resources() function takes a  cookie  representing  a snapshot
       of the lgroup hierarchy obtained from lgrp_init(3LGRP) and returns  the
       number of resources in the lgroup specified by lgrp.  The resources are
       represented by a set of lgroups in which each lgroup directly  contains
       CPU and/or memory resources.

       The type argument should be set to one of the following values to spec‐
       ify whether the CPU or memory resources should be returned:

	 LGRP_RSRC_CPU	    /* CPU resources */
	 LGRP_RSRC_MEM	    /* Memory resources */

       If the lgrpids[] argument is non-null and the count  argument  is  non-
       zero,  lgrp_resources()	stores up to the specified count of lgroup IDs
       into the lgrpids[] array.

RETURN VALUES
       Upon  successful	 completion,  lgrp_resources() returns the number   of
       lgroup  resources.  Otherwise, -1 is returned and errno is set to indi‐
       cate the error.

ERRORS
       The lgrp_resources() function will fail if:

       EINVAL
		 The specified cookie, lgroup  ID, or type is not valid.

       ESRCH
		 The specified lgroup ID was not found.
