META(3XCURSES)META(3XCURSES)NAMEmeta - enable/disable meta keys
SYNOPSIS
cc [ flag... ] file... -I /usr/xpg4/include -L /usr/xpg4/lib \
-R /usr/xpg4/lib -lcurses [ library... ]
c89 [ flag... ] file... -lcurses [ library... ]
#include <curses.h>
int meta(WINDOW *win, bool bf);
PARAMETERS
win
Is an ignored parameter.
bf
Is a Boolean expression.
DESCRIPTION
Whether a terminal returns 7 or 8 significant bits initially depends on
the control mode of the terminal driver. The meta() function forces
the number of bits to be returned by getch(3XCURSES) to be 7 (if bf is
FALSE) or 8 (if bf is TRUE).
If the program handling the data can only pass 7-bit characters or
strips the 8th bit, 8 bits cannot be handled.
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.
This function is useful when extending the non-text command set in
applications where the META key is used.
RETURN VALUES
On success, the meta() function returns OK. Otherwise, it returns ERR.
ERRORS
None.
