GETLABELSECTOR(3) BSD Library Functions Manual GETLABELSECTOR(3)
NAME
getlabelsector, getlabeloffset, getlabelusesmbr -- get disklabel location informations
LIBRARY
System Utilities Library (libutil, -lutil)
SYNOPSIS
#include <util.h>
daddr_t
getlabelsector(void);
off_t
getlabeloffset(void);
int
getlabelusesmbr(void);
DESCRIPTION
The getlabelsector() and getlabeloffset() functions return values which describe the exact on-disk location of the disklabel(5) on the cur-
rent system, or -1 on error. These functions supersede the hardcoded LABELSECTOR and LABELOFFSET definitions previously used to derive the
location of the disklabel(5).
The getlabelusesmbr() returns 1 if the disklabel is located inside a MBR partition, 0 if it's stored relative to the start of the disk, or -1
on error.

HISTORY
The getlabelsector() and getlabeloffset() functions appeared in NetBSD 2.0.
