#include <sys/lgrp_user.h>

int lgrp_children(lgrp_cookie_t cookie, lgrp_id_t parent,

DESCRIPTION

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.
