<H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       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  specified).   (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  specifies  only  "an integer value other than <STRONG>ERR</STRONG>")
       upon successful completion.

       Functions with a "mv" prefix first perform a cursor  move-
       ment  using  <STRONG>wmove</STRONG>, and return an error if the position is
       outside the window, or if the window pointer is null.


</PRE>
<H2><a name="h2-NOTES">NOTES</a></H2><PRE>
       Note that <STRONG>delch</STRONG>, <STRONG>mvdelch</STRONG>, and <STRONG>mvwdelch</STRONG> may be macros.


</PRE>
<H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
       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.
