keypad - enable/disable abbreviation of function keys


#include <curses.h>

int keypad(WINDOW *win, bool bf);


The keypad() function 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 function affects the behaviour 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 implementation transmits this command to the terminal before an affected input function tries to read any characters from that terminal.


Upon successful completion, keypad() returns OK. Otherwise, it returns ERR.


No errors are defined.
