<H2>NAME</H2><PRE>
<STRONG>key_defined</STRONG> - check if a keycode is defined
</PRE>
<H2>SYNOPSIS</H2><PRE>
<STRONG>#include</STRONG> <STRONG><curses.h></STRONG>
<STRONG>int</STRONG> <STRONG>key_defined(const</STRONG> <STRONG>char</STRONG> <STRONG>*definition);</STRONG>
</PRE>
<H2>DESCRIPTION</H2><PRE>
This is an extension to the curses library. It permits an
application to determine if a string is currently bound to
any keycode.
</PRE>
<H2>RETURN VALUE</H2><PRE>
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.
</PRE>
<H2>PORTABILITY</H2><PRE>
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 con-
ditioned using NCURSES_VERSION.
