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.

SEE ALSO

sysctl(3), disklabel(5)

HISTORY

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