#include <sys/lgrp_user.h>

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

The lgrp_children() function returns the number of child lgroup IDs. Otherwise, it returns −1 and sets errno to indicate the error.
