.SH NAME
|
||||
termio \- the System V terminal driver interface
|
||||
.SH DESCRIPTION
|
||||
.B termio
|
||||
is the name of the old System V terminal driver interface.
|
||||
This interface defined a
|
||||
.I termio
|
||||
structure used to store terminal settings, and a range of
|
||||
.BR ioctl (2)
|
||||
operations to get and set terminal attributes.
|
||||
|
||||
The
|
||||
.B termio
|
||||
interface is now obsolete: POSIX.1-1990 standardized a modified
|
||||
version of this interface, under the name
|
||||
.BR termios .
|
||||
The POSIX.1 data structure differs slightly from the
|
||||
System V version, and POSIX.1 defined a suite of functions
|
||||
to replace the various
|
||||
.BR ioctl ()
|
||||
operations that existed in System V.
|
||||
(This was done because
|
||||
.BR ioctl ()
|
||||
was unstandardised, and its variadic third argument
|
||||
does not allow argument type checking.)
|
||||
|
||||
If you're looking for page called "termio", then you can probably
|
||||
find most of the information that you seek in either
|
||||
.BR termios (3)
|
||||
or
|
||||
.BR tty_ioctl (4).

||||

||||
