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 <EM>y</EM>, <EM>x</EM>, if speci-
fied). (This does not imply use of the hardware delete character fea-
ture.)
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
All routines return the integer <STRONG>ERR</STRONG> upon failure and an <STRONG>OK</STRONG> (SVr4 speci-
fies only "an integer value other than <STRONG>ERR</STRONG>") upon successful comple-
tion.
Functions with a "mv" prefix first perform a cursor movement using
<STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
the window pointer is null.

Note that <STRONG>delch</STRONG>, <STRONG>mvdelch</STRONG>, and <STRONG>mvwdelch</STRONG> may be macros.

These functions are described in the XSI Curses standard, Issue 4. The
standard specifies that they return <STRONG>ERR</STRONG> on failure, but specifies no
error conditions.
