| .SH NAME |
| \fBkey_defined\fP \- check if a keycode is defined |
| .SH SYNOPSIS |
| \fB#include <curses.h>\fP |
| .sp |
| \fBint key_defined(const char *definition);\fP |
| .SH DESCRIPTION |
| This is an extension to the curses library. |
| It permits an application to determine if a string is currently bound |
| to any keycode. |
| .SH RETURN VALUE |
| If the string is bound to a keycode, its value (greater than zero) is returned. |
| If no keycode is bound, zero is returned. |
| If the string conflicts with longer strings which are bound to keys, \-1 is returned. |
| .SH 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. |
