+<H2>DESCRIPTION</H2><PRE>
+ The <EM>use</EM><STRONG>_</STRONG><EM>legacy</EM><STRONG>_</STRONG><EM>coding()</EM> function is an extension to the
+ curses library. It allows the caller to change the result
+ of <STRONG>unctrl</STRONG>, and suppress related checks within the library
+ that would normally cause nonprinting characters to be
+ rendered in visible form. This affects only 8-bit charac-
+ ters.
+
+ The <EM>level</EM> parameter controls the result:
+
+ 0 the library functions normally, rendering non-
+ printing characters as described in <STRONG>unc-</STRONG>
+ <STRONG><A HREF="unctrl.3x.html">trl(3x)</A></STRONG>.
+
+ 1 the library ignores <STRONG>isprintf</STRONG> for codes in the
+ range 160-255.
+
+ 2 the library ignores <STRONG>isprintf</STRONG> for codes in the
+ range 128-255. It also modifies the output of
+ <STRONG>unctrl</STRONG>, showing codes in the range 128-159 as
+ is.
+
+
+</PRE>
+<H2>RETURN VALUE</H2><PRE>
+ If the screen has not been initialized, or the <EM>level</EM>
+ parameter is out of range, the function returns <STRONG>ERR</STRONG>. Oth-
+ erwise, it returns the previous level: <STRONG>0</STRONG>, <STRONG>1</STRONG> or <STRONG>2</STRONG>.
+
+
+</PRE>
+<H2>PORTABILITY</H2><PRE>
+ This routine is specific to ncurses. It was not supported
+ on Version 7, BSD or System V implementations. It is rec-
+ ommended that any code depending on ncurses extensions be
+ conditioned using NCURSES_VERSION.
