34 \fBkey_defined\fP \- check if a keycode is defined

40 This is an extension to the curses library.
41 It permits an application to determine if a string is currently bound
44 If the string is bound to a keycode, its value (greater than zero) is returned.
45 If no keycode is bound, zero is returned.
46 If the string conflicts with longer strings which are bound to keys, \-1 is returned.
48 These routines are specific to ncurses. They were not supported on
49 Version 7, BSD or System V implementations. It is recommended that
50 any code depending on them be conditioned using NCURSES_VERSION.
