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 current 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.
