-<H2>DESCRIPTION</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>RETURN VALUE</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.

-<H2>PORTABILITY</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.
