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.</PRE><H2>SEE ALSO</H2><PRE> <STRONG><A HREF="define_key.3x.html">define_key(3x)</A></STRONG>.</PRE><H2>AUTHOR</H2><PRE> Thomas Dickey. <STRONG><A HREF="key_defined.3x.html">key_defined(3x)</A></STRONG></PRE><HR><ADDRESS>Man(1) output converted with<a href="http://www.oac.uci.edu/indiv/ehood/man2html.html">man2html</a></ADDRESS></BODY></HTML>⌨️ 快捷键说明
