key_defined(3X) key_defined(3X) NAME define_key - define a keycode SYNOPSIS #include <curses.h> int key_defined(const char *definition); DESCRIPTION This is an extension to the curses library. It permits an application to determine if(3,n) a string(3,n) is currently bound to any keycode. RETURN VALUE If the string(3,n) is bound to a keycode, its value (greater than zero) is returned. If no keycode is bound, zero is returned. If the string(3,n) conflicts with longer strings which are bound to keys, -1 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 define_key(3X).
