NAME
lgrp_children - get children of given lgroup SYNOPSIS
cc [ flag ... ] file... -llgrp [ library ... ] #include <sys/lgrp_user.h> int lgrp_children(lgrp_cookie_t cookie, lgrp_id_t parent, lgrp_id_t *lgrp_array, uint_t lgrp_array_size); DESCRIPTION
The lgrp_children() function takes a cookie representing a snapshot of the lgroup hierarchy retrieved from lgrp_init(3LGRP) and returns the number of lgroups that are children of the specified lgroup. If the lgrp_array and lgrp_array_size arguments are non-null, the array is filled with as many of the children lgroup IDs as will fit, given the size of the array. RETURN VALUES
- returns the number of child lgroup IDs. Otherwise, it returns -1 and sets errno to indicate the error. ERRORS
The lgrp_children() function will fail if: EINVAL The specified lgroup ID is not valid or the cookie is invalid. ESRCH The specified lgroup ID was not found. ATTRIBUTES

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); 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 specify 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. Upon successful completion, lgrp_resources() returns the number of lgroup resources. Otherwise, -1 is returned and errno is set to indicate the error. 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.
