-<H2>DESCRIPTION</H2><PRE>
- These routines, insert the complex character <EM>wch</EM> with ren-
- dition before the character under the cursor. All charac-
- ters to the right of the cursor are moved one space to the
- right, with the possibility of the rightmost character on
- the line being lost. The insertion operation does not
- change the cursor position.
+</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
+ These functions insert the <EM>curses</EM> complex character <EM>wch</EM> at the cursor
+ in the specified window <EM>win</EM> (or <STRONG>stdscr</STRONG>). The character previously at
+ the cursor and any to its right move one cell to the right; the
+ rightmost character on the line is discarded. The cursor does not
+ advance.
-</PRE>
-<H2>RETURN VALUE</H2><PRE>
- If successful, these functions return OK. If not, they
- return ERR.
+</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
+ These functions return <STRONG>OK</STRONG> on success and <STRONG>ERR</STRONG> on failure.
+ Functions taking a <EM>WINDOW</EM> pointer argument fail if the pointer is <STRONG>NULL</STRONG>.
-</PRE>
-<H2>ERRORS</H2><PRE>
- No errors are defined.
+ Functions prefixed with "mv" first perform cursor movement using <STRONG>wmove</STRONG>
+ and fail if the position (<EM>y</EM>, <EM>x</EM>) is outside the window.
