- get lgroup resources of given lgroup
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:
The specified cookie is NULL, or the lgroup ID or type is not valid.
The specified lgroup ID was not found.
