+ <B>keyok</B> - enable or disable a keycode
+
+
+</PRE>
+<H2>SYNOPSIS</H2><PRE>
+ <B>#include</B> <B><curses.h></B>
+
+ <B>int</B> <B>keyok(int</B> <B>keycode,</B> <B>bool</B> <B>enable);</B>
+
+
+</PRE>
+<H2>DESCRIPTION</H2><PRE>
+ This is an extension to the curses library. It permits an
+ application to disable specific keycodes, rather than use
+ the <I>keypad</I> function to disable all keycodes. Keys that
+ have been disabled can be reenabled.
+
+
+</PRE>
+<H2>RETURN VALUE</H2><PRE>
+ The keycode must be greater than zero, else ERR is
+ returned. If it does not correspond to a defined key,
+ then ERR is returned. If the <I>enable</I> parameter is true,
+ then the key must have been disabled, and vice versa.
+ Otherwise, the function returns OK.
+
+
+</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.
