- get children of given lgroup
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);
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.
The lgrp_children() function returns the number of child lgroup IDs. Otherwise, it returns -1 and sets errno to indicate the error.
The lgrp_children() function will fail if:
The specified lgroup ID is not valid or the cookie is NULL.
The specified lgroup ID was not found.
