int use_legacy_coding(int level);
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 charac-
The level parameter controls the result:
0 the library functions normally, rendering non-
printing characters as described in unctrl.
1 the library ignores isprintf for codes in the
2 the library ignores isprintf for codes in the
range 128-255. It also modifies the output of
unctrl, showing codes in the range 128-159 as
If the screen has not been initialized, or the level
parameter is out of range, the function returns ERR. Oth-
erwise, it returns the previous level: 0, 1 or 2.
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.
