Tioclinux() uses "magic numbers" that applications should know to use it.
Here is a patch which adds an include/linux/tiocl.h which holds them and
can be used by applications to properly call iotcl(TIOCLINUX).  It might
stand for documentation as well, replacing the not up-to-date man
ioctl_list.

A structure for the selection argument is also defined.
