.SH NAME
|
|
\fBkey_defined\fP \- check if a keycode is defined
|
|
.SH SYNOPSIS
|
|
\fB#include <curses.h>\fP
|
|
.sp
|
|
\fBint key_defined(const char *\fP\fIdefinition\fP\fB);\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.
