| 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>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. |
| |

| <H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></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>. |

| 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. |
