NAME
meta — enable/disable meta-keys
SYNOPSIS
#include <curses.h>
int meta(WINDOW *win, bool bf);
DESCRIPTION
Initially, whether the terminal returns 7 or 8 significant bits on input
depends on the control mode of the display driver (see the
X/Open System Interface Definitions, Issue 4, Version 2
specification,
General Terminal Interface).
To force 8 bits to be returned, invoke meta(win, TRUE).
To force 7 bits to be returned, invoke meta(win, FALSE).
The win argument is always ignored. If the terminfo capabilities
smm (meta_on) and rmm (meta_off) are defined for the terminal,
smm is sent to the terminal when meta(win, TRUE) is called
and rmm is sent when meta(win, FALSE) is called.
RETURN VALUE
Upon successful completion,
meta()
returns OK. Otherwise, it returns ERR.
ERRORS
No errors are defined.
APPLICATION USAGE
The same effect is achieved outside Curses using the CS7 or CS8 control mode
flag specified in the
X/Open System Interface Definitions, Issue 4, Version 2
specification (
General Terminal Interface).
The
meta()
function was designed for use with terminals with 7-bit character sets and
a ``meta'' key that could be used to set the eighth bit.
