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>unctrl</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. </PRE> <H2>SEE ALSO</H2><PRE> <STRONG>unctrl</STRONG>. </PRE> <H2>AUTHOR</H2><PRE> Thomas Dickey (to support lynx's font-switching feature). <STRONG><A HREF="legacy_coding.3x.html">legacy_coding(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>
