Usage
#include <curses.h>
int use_legacy_coding(int level);
Overview
The use_legacy_coding() function is an extension to the curses library. It allows the caller to change the result of unctrl, and suppress related checks within the library that would normally cause nonprinting characters to be rendered in visible form. This affects only 8-bit characters.
The level parameter controls the result:
- 0
-
the library functions normally, rendering nonprinting characters as described in
unctrl.
- 1
-
the library ignores
isprintffor codes in the range 160-255.
- 2
-
the library ignores
isprintffor codes in the range 128-255. It also modifies the output ofunctrl, showing codes in the range 128-159 as is.
Return value
If the screen has not been initialized, or the level parameter is out of range, the function returns ERR. Otherwise, it returns the previous level: 0, 1 or 2.
Portability
This routine is specific to ncurses. It was not supported on Version 7, BSD or System V implementations. It is recommended that any code depending on ncurses extensions be conditioned using NCURSES_VERSION.
