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