BSD Terminal Modes
==================

   The usual way to get and set terminal modes is with the functions
described in Note: 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'.

 - Data Type: struct sgttyb
     This structure is an input or output parameter list for `gtty' and
     `stty'.

    `char sg_ispeed'
          Line speed for input

    `char sg_ospeed'
          Line speed for output

    `char sg_erase'
          Erase character

    `char sg_kill'
          Kill character

    `int sg_flags'
          Various flags

 - Function: int gtty (int FILEDES, struct sgttyb *ATTRIBUTES)
     This function gets the attributes of a terminal.

     `gtty' sets *ATTRIBUTES to describe the terminal attributes of the
     terminal which is open with file descriptor FILEDES.

 - Function: int stty (int FILEDES, struct sgttyb * attributes)
     This function sets the attributes of a terminal.

     `stty' sets the terminal attributes of the terminal which is open
     with file descriptor FILEDES to those described by *FILEDES.
