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.
- 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:
EINVAL
The specified lgroup ID is not valid or the cookie is invalid.
ESRCH
The specified lgroup ID was not found.
