gtty

STTY(3) 						   BSD Library Functions Manual 						   STTY(3)

NAME

     stty, gtty -- set and get terminal state (defunct)

LIBRARY

     Compatibility Library (libcompat, -lcompat)

SYNOPSIS

     #include <sgtty.h>

     stty(int fd, struct sgttyb *buf);

     gtty(int fd, struct sgttyb *buf);

DESCRIPTION

     These interfaces are obsoleted by ioctl(2).  They are available from the compatibility library, libcompat.

     The stty() function sets the state of the terminal associated with fd.  The gtty() function retrieves the state of the terminal associated
     with fd.  To set the state of a terminal the call must have write permission.

     The stty() call is actually 'ioctl(fd, TIOCSETP, buf)', while the gtty() call is 'ioctl(fd, TIOCGETP, buf)'.  See ioctl(2) and tty(4) for an
     explanation.

DIAGNOSTICS

     If the call is successful 0 is returned, otherwise -1 is returned and the global variable errno contains the reason for the failure.

SEE ALSO

     ioctl(2), tty(4)

HISTORY

     The stty() and gtty() functions appeared in 4.2BSD.
