The erasechar() function returns the current ERASE character from the

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 cur‐
rent 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. Oth‐
erwise, they return ERR.
