62 <H2>DESCRIPTION
</H2><PRE>
63 This is an extension to the curses library. It permits an
64 application to determine if a string is currently bound to
69 <H2>RETURN VALUE
</H2><PRE>
70 If the string is bound to a keycode, its value (greater
71 than zero) is returned. If no keycode is bound, zero is
72 returned. If the string conflicts with longer strings
73 which are bound to keys, -
1 is returned.
77 <H2>PORTABILITY
</H2><PRE>
78 These routines are specific to ncurses. They were not
79 supported on Version
7, BSD or System V implementations.
80 It is recommended that any code depending on them be con-
81 ditioned using NCURSES_VERSION.
