DESCRIPTION
The

the tty driver. This character is used to delete the previous
character during keyboard input. The returned value can be used when
including deletion capability in interactive programs.
The
killchar() function is similar to
erasechar(). It returns the
current KILL character.
The
erasewchar() and
killwchar() functions are similar to
erasechar() and
killchar() respectively, but store the ERASE or KILL character
in the object pointed to by
ch.
PARAMETERS
ch Is a pointer to a location where a character may be stored.
RETURN VALUES
For
erasechar() and
killchar(), the terminal's current ERASE or KILL
character is returned.
On success, the
erasewchar() and
killwchar() functions return
OK.
Otherwise, they return
ERR.
