meta 

The meta routine is used to control the number of bits returned on input.

Syntax 

     #include <curses.h>

     int meta(WINDOW *win, bool bf);

Parameters 

bf                    A Boolean expression.

win                   An ignored parameter.

Return Values 

OK                    Successful completion.

ERR                   An error occurred.  The terminal or system cannot
                      handle 8-bit character codes.

Description 

Whether a terminal returns 7 or 8 significant bits initially depends on
the control mode of the terminal driver.  The meta() routine forces the
number of bits to be returned by getch() to be 7 (if bf is FALSE) or 8
(if bf is TRUE).


NOTE  If the program handling the data can pass only 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 routine is useful when extending the nontext command set in
applications where the META key is used.


NOTE  The meta() routine is provided for compatability with older CURSES
      packages.  The MPE/iX CURSES package handles 16-bit characters,
      therefore making this function unnecessary.
