GETLABELSECTOR(3)       NetBSD Library Functions Manual      GETLABELSECTOR(3)


NAME

     getlabelsector, getlabeloffset -- get the sector number and offset of the
     disklabel


LIBRARY

     System Utilities Library (libutil, -lutil)


SYNOPSIS

     #include <util.h>

     daddr_t
     getlabelsector(void);

     off_t
     getlabeloffset(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 supercede the hardcoded
     LABELSECTOR and LABELOFFSET definitions previously used to derive the
     location of the disklabel(5).


SEE ALSO

     sysctl(3), disklabel(5)
