STANDARDS top

   Linux.

CAVEATS top

   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.
