Enables or disables abbreviation of function keys.
Curses Library (libcurses.a)
#include <curses.h>int keypad(WINDOW *win,
bool bf);
The keypad subroutine controls keypad translation. If bf is TRUE, keypad translation is turned on. If bf is FALSE, keypad translation is turned off. The initial state is FALSE.
This subroutine affects the behavior of any function that provides keyboard input.
If the terminal in use requires a command to enable it to transmit distinctive codes when a function key is pressed, then after keypad translation is first enabled, the implemenation transmits this command to the terminal before an affected input function tries to read any characters from that terminal.
| Item | Description |
|---|---|
| bf | |
| *win | Specifies the window in which to enable or disable the keypad. |
Upon successful completion, the keypad subroutine returns OK. Otherwise, it returns ERR.
To turn on the keypad in the user-defined window my_window, use:
WINDOW *my_window;
keypad(my_window, TRUE);
