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

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.

Otherwise, they return ERR.
