keypad

The keypad routine is used to enable keypad handling.

Syntax

   #include <curses.h>



   int keypad(WINDOW *win, bool bf);

Parameters

win: A pointer to the window in which to enable keypad handling.
bf: A Boolean expression.

Return Values

OK: Successful completion.
ERR: An error occurred.

Description

If bf is TRUE, keypad() handles special keys from the keyboard on the terminal associated with win as single values instead of character sequences. For example, if the user presses the right arrow key, wgetch() returns a single value, KEY_RIGHT, that represents the function key; otherwise, CURSES handles the special keys as normal text.

See wgetch() for a list of tokens for function keys that are returned by getch().
