.SH DESCRIPTION
These routines delete the character under the cursor; all characters to the
right of the cursor on the same line are moved to the left one position and the
last character on the line is filled with a blank.
The cursor position does
-not change (after moving to \fIy\fR, \fIx\fR, if specified).

(This does not

.PP
Functions with a \*(``mv\*('' prefix first perform a cursor movement using
\fBwmove\fP, and return an error if the position is outside the window,
or if the window pointer is null.

These functions are described in the XSI Curses standard, Issue 4.
