<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
ncurses 5.3
2002-10-13 11:35:53 +08:00
not change (after moving to <EM>y</EM>, <EM>x</EM>, if specified). (This
ncurses 5.1
2000-07-09 10:46:08 +08:00
does not imply use of the hardware delete character fea-
ture.)
</PRE>
<H2>RETURN VALUE</H2><PRE>
ncurses 5.3
2002-10-13 11:35:53 +08:00
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>")
ncurses 5.1
2000-07-09 10:46:08 +08:00
upon successful completion.
ncurses 5.7 - patch 20100918 + regenerated html manpages. + minor fixes for symlinks to curs_legacy.3x and curs_slk.3x manpages. + add manpage for sp-funcs. + add sp-funcs to test/listused.sh, for documentation aids.
2010-09-19 08:45:46 +08:00
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.

<H2>NOTES</H2><PRE>
ncurses 5.3
2002-10-13 11:35:53 +08:00
Note that <STRONG>delch</STRONG>, <STRONG>mvdelch</STRONG>, and <STRONG>mvwdelch</STRONG> may be macros.
ncurses 5.1
2000-07-09 10:46:08 +08:00
</PRE>
<H2>PORTABILITY</H2><PRE>
These functions are described in the XSI Curses standard,
ncurses 5.3
2002-10-13 11:35:53 +08:00
Issue 4. The standard specifies that they return <STRONG>ERR</STRONG> on
ncurses 5.1
2000-07-09 10:46:08 +08:00
failure, but specifies no error conditions.
