</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
These functions write the (null-terminated) character string <EM>str</EM> on the
given window. It is similar to calling <STRONG>waddch</STRONG> once for each byte in
the string.
The <EM>mv</EM> functions perform cursor movement once, before writing any char-
acters. Thereafter, the cursor is advanced as a side-effect of writing
to the window.
The four functions with <EM>n</EM> as the last argument write at most <EM>n</EM> bytes,
or until a terminating null is reached. If <EM>n</EM> is -1, then the entire
string will be added.
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
All functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success.
X/Open does not define any error conditions. This implementation re-
turns an error
<STRONG>o</STRONG> if the window pointer is null or
<STRONG>o</STRONG> if the string pointer is null or
<STRONG>o</STRONG> if the corresponding calls to <STRONG>waddch</STRONG> return an error.
Functions with a "mv" prefix first perform a cursor movement using
<STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
the window pointer is null. If an error is returned by the <STRONG>wmove</STRONG>, no
characters are added to the window.
If an error is returned by <STRONG>waddch</STRONG> (e.g., because the window is not
large enough, or an illegal byte sequence was detected) only part of
the string may be added. Aside from that, there is a special case in
<STRONG>waddch</STRONG> where an error may be returned after successfully writing a
character to the lower-right corner of a window when <STRONG>scrollok</STRONG> is dis-
abled.
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
All of these functions except <STRONG>waddnstr</STRONG> may be macros.

These functions are described in the XSI Curses standard, Issue 4.
