#include <sys/lgrp_user.h>
int lgrp_children(lgrp_cookie_t cookie, lgrp_id_t parent, lgrp_id_t

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.
