perform wrapping and special-character processing as fol-
lows:
- - If <EM>wch</EM> refers to a spacing character, then any previ-
- ous character at that location is removed. A new
- character specified by <EM>wch</EM> is placed at that location
- with rendition specified by <EM>wch</EM>. The cursor then
- advances to the next spacing character on the screen.

- - If <EM>wch</EM> refers to a non-spacing character, all previ-
- ous characters at that location are preserved. The
- non-spacing characters of <EM>wch</EM> are added to the spac-
- ing complex character, and the rendition specified by
- <EM>wch</EM> is ignored.

- backspace or other control character, the window is
- updated and the cursor moves as if <STRONG>addch</STRONG> were called.

The <STRONG>echo_wchar</STRONG> function is functionally equivalent to a
call to <STRONG>add_wch</STRONG> followed by a call to <STRONG>refresh</STRONG>. Similarly,
All routines return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on
success.
+ 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.
