.SH DESCRIPTION
.sp
.LP
The \fBerasechar()\fR function returns the current ERASE character  from 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.
.sp
.LP
The \fBkillchar()\fR function is similar to \fBerasechar()\fR. It returns the
current KILL character.
.sp
.LP
The \fBerasewchar()\fR and \fBkillwchar()\fR functions are similar to
\fBerasechar()\fR and \fBkillchar()\fR respectively, but store the  ERASE or
KILL character in the object pointed to by \fIch\fR.
