DESCRIPTION
Thegetlabelsector()
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.
