define_key(y) define_key(y) NAME define_key - define a keycode SYNOPSIS #include <curses.h> int define_key(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 inter- pret 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, else ERR 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 con- ditioned using NCURSES_VERSION. SEE ALSO keyok(k). AUTHOR Thomas Dickey. define_key(y)
