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.

SEE ALSO
     sysctl(3), disklabel(5)

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