| 33 | .SH NAME |
| 34 | \fBkey_defined\fP \- check if a keycode is defined |
| 35 | .SH SYNOPSIS |
| 36 | \fB#include <curses.h>\fP |
| 37 | .sp |
| 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. |
| Steve Kondik | ae271bc | 2015-11-15 02:50:53 +0100 | [diff] [blame] | 46 | If the string conflicts with longer strings which are bound to keys, \-1 is returned. |
| Amit Daniel Kachhap | e6a01f5 | 2011-07-20 11:45:59 +0530 | [diff] [blame] | 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. |
