GETLABELSECTOR(3) 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 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. NetBSD 9.99 August 25, 2011 NetBSD 9.99
