keyok(3ncurses) [bsd man page]

keyok(3NCURSES) 														   keyok(3NCURSES)

NAME
keyok - enable or disable a keycode SYNOPSIS
#include <curses.h> int keyok(int keycode, bool enable); DESCRIPTION
This is an extension to the curses library. It permits an application to disable specific keycodes, rather than use the keypad function to disable all keycodes. Keys that have been disabled can be re-enabled. RETURN VALUE
The keycode must be greater than zero, else ERR is returned. If it does not correspond to a defined key, then ERR is returned. If the enable parameter is true, then the key must have been disabled, and vice versa. Otherwise, the function returns OK. PORTABILITY
These routines are specific to ncurses. They were not supported on Version 7, BSD or System V implementations. It is recommended that any code depending on them be conditioned using NCURSES_VERSION. SEE ALSO

NAME
define_key - define a keycode SYNOPSIS
#include <curses.h> int define_key(const char *definition, int keycode); DESCRIPTION
This is an extension to the curses library. It permits an application to define keycodes with their corresponding control strings, so that the ncurses library will interpret them just as it would the predefined codes in the terminfo database. If the given string is null, any existing definition for the keycode is removed. Similarly, if the given keycode is negative or zero, any existing string for the given definition is removed. RETURN VALUE
The keycode must be greater than zero, and the string non-null, otherwise ERR is returned. ERR may also be returned if there is insuffi- cient memory to allocate the data to store the definition. If no error is detected, OK is returned. PORTABILITY
These routines are specific to ncurses. They were not supported on Version 7, BSD or System V implementations. It is recommended that any code depending on them be conditioned using NCURSES_VERSION. SEE ALSO
