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.
