| 35 | .SH SYNOPSIS
|
|---|
| 36 | \fB#include <curses.h>\fP
|
|---|
| 37 |
|
|---|
| 38 | \fBint key_defined(const char *definition);\fP
|
|---|
| 39 | .SH DESCRIPTION
|
|---|
| 40 | This is an extension to the curses library.
|
|---|
| 41 | It permits an application to determine if a string is currently bound
|
|---|
| 42 | to any keycode.
|
|---|
| 43 | .SH RETURN VALUE
|
|---|
| 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.
|
|---|
| 47 | .SH PORTABILITY
|
|---|
| 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.
