STANDARDS
Linux.
CAVEATS
Do not regard this man page as documentation of the Linux console ioctls.
This is provided for the curious only, as an alternative to reading the
source.
Ioctl's are undocumented Linux internals, liable to be changed
without warning.
(And indeed, this page more or less describes the
situation as of kernel version 1.1.94;
there are many minor and no-s-minor
differences with earlier versions.)
Very often, ioctls are introduced for communication between the
kernel and one particular wel-known program (fdisk, hdparm, setserial,
tunelp, loadkeys, selection, setfont, etc.), and their behavior will be
changed when required by this particular program.
