|
|
<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.
|
|
|
|
|
|
</PRE>
|
|
<H2>NOTES</H2><PRE>
|
|
Note that <STRONG>delch</STRONG>, <STRONG>mvdelch</STRONG>, and <STRONG>mvwdelch</STRONG> may be macros.
|
|
|
|
|
|
</PRE>
|
|
<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.
