GETLABELSECTOR(3) BSD Library Functions Manual GETLABELSECTOR(3)NAME
getlabelsector, getlabeloffset, getlabelusesmbr -- get disklabel location informations
System Utilities Library (libutil, -lutil)
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
SEE ALSO sysctl(3), disklabel(5)HISTORY
The getlabelsector() and getlabeloffset() functions appeared in NetBSD 2.0.

GETDISKBYNAME(3) BSD Library Functions Manual GETDISKBYNAME(3)NAME
getdiskbyname, setdisktab -- get generic disk description by its name
Standard C Library (libc, -lc)
struct disklabel *
getdiskbyname(const char *name);
The getdiskbyname() function takes a disk name (e.g. 'rm03') and returns a prototype disk label describing its geometry information and the
standard disk partition tables. All information is obtained from the disktab(5) file.
The setdisktab() function changes the default disktab file name from /etc/disktab (aka _PATH_DISKTAB) to name.
getdiskbyname() returns a null pointer if the entry is not found in the current disktab file.
setdisktab() returns 0 on success and -1 if name is a null pointer or points to an empty string.
/etc/disktab the default database of disk types.
SEE ALSO disklabel(5), disktab(5), disklabel(8)HISTORY
The getdiskbyname() function appeared in 4.3BSD.
The setdisktab() function appeared in NetBSD 1.4.
The getdiskbyname() function leaves its results in an internal static object and returns a pointer to that object. Subsequent calls will
modify the same object.

I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
