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 not-so-minor differences with earlier
versions.)
Very often, ioctls are introduced for communication between the
kernel and one particular well-known program (fdisk, hdparm,
setserial, tunelp, loadkeys, selection, setfont, etc.), and their
behavior will be changed when required by this particular
program.
