NAME
stty(), gtty() — control terminal device (Bell Version 6 compatibility)
SYNOPSIS
#include <sgtty.h>
int stty(int fildes, const struct sgttyb *argp);
int gtty(int fildes, struct sgttyb *argp);
Remarks
These system calls are preserved for backward compatibility
with Bell Version 6.
They provide as close an approximation as possible
to the old Version 6 functions.
All new code should use the
TCSETA
and
TCGETA
ioctl()
calls described in
termio(7).
DESCRIPTION
For certain status settings and status inquiries about terminal devices,
the functions
stty()
and
gtty()
are equivalent to
ioctl(fildes, TIOCSETP, argp)
and
ioctl(fildes, TIOCGETP, argp)
respectively (see
ioctl(2)
and
termio(7).
RETURN VALUE
gtty()
and
stty()
return the following values:
- 0
Successful completion.
- -1
Failure.
errno
is set to indicate the error.
ERRORS
If
gtty()
or
stty()
fails,
errno
is set to one of the following values:
- [EBADF]
fildes
is not a valid file descriptor.
- [EFAULT]
argp
points to an invalid address.
