NAME

liblgrp - locality group library

SYNOPSIS

cc [ flag... ] file... -llgrp [ library... ]
#include <sys/lgrp_user.h>

DESCRIPTION

The functions in this library traverse the lgroup (locality group)
hierarchy, discover its contents, and set a thread's affinity for an
lgroup. A locality group represents the set of CPU-like and memory-
like hardware devices that are at most some locality apart from each
other.
