The usual way to get and set terminal modes is with the functions described
in Terminal Modes. However, on some systems you can use the
BSD-derived functions in this section to do some of the same thing. On
many systems, these functions do not exist. Even with the GNU C Library,
the functions simply fail with errno
= ENOSYS
with many
kernels, including Linux.
The symbols used in this section are declared in sgtty.h.
