NAME
erasechar, killchar — single-byte terminal environment query functions
SYNOPSIS
#include <curses.h>
char erasechar(void);
char killchar(void);
DESCRIPTION
The erasechar() function returns the current erase character. The
erasewchar() function stores
the current erase character in the object pointed to by ch. If no erase character has been defined, the
function will fail and the object pointed to by ch will not be changed.
The
killchar() function returns the current line kill character.
RETURN VALUE
The
erasechar() function returns the erase character and
killchar() returns the line kill charac-
ter. The return value is unspecified when these characters are multi-byte characters.
ERRORS
No errors are defined.
APPLICATION USAGE
The
erasechar() and killchar() functions are only guaranteed to operate reliably on character
sets in which each character fits into a single byte, whose attributes can be expressed using only con-
stants with the A_ prefix. Moreover, they do not reliably indicate cases in which when the erase or line
kill character, respectively, has not been defined. The
erasewchar() and killwchar() functions
overcome these limitations.

CHANGE HISTORY
First released in X/Open Curses, Issue 2.
X/Open Curses, Issue 4
The
killchar() function is merged with this entry. In previous issues, it appeared in an entry of its
own.
The entry is rewritten for clarity. The argument list for the
erasechar() and killchar() functions
is explicitly declared as void.
