<H2>NAME</H2><PRE>
<STRONG>delch</STRONG>, <STRONG>wdelch</STRONG>, <STRONG>mvdelch</STRONG>, <STRONG>mvwdelch</STRONG> - delete character under
the cursor in a <STRONG>curses</STRONG> window
</PRE>
<H2>SYNOPSIS</H2><PRE>
<STRONG>#include</STRONG> <STRONG><curses.h></STRONG>
<STRONG>int</STRONG> <STRONG>delch(void);</STRONG>
<STRONG>int</STRONG> <STRONG>wdelch(WINDOW</STRONG> <STRONG>*win);</STRONG>
<STRONG>int</STRONG> <STRONG>mvdelch(int</STRONG> <STRONG>y,</STRONG> <STRONG>int</STRONG> <STRONG>x);</STRONG>
<STRONG>int</STRONG> <STRONG>mvwdelch(WINDOW</STRONG> <STRONG>*win,</STRONG> <STRONG>int</STRONG> <STRONG>y,</STRONG> <STRONG>int</STRONG> <STRONG>x);</STRONG>
</PRE>
<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.
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>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.
