- 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 character in the string.
- The <EM>mv</EM> functions perform cursor movement once, before
- writing any characters. Thereafter, the cursor is ad-
- vanced as a side-effect of writing to the window.

- All of these functions except <STRONG>waddnstr</STRONG> may be macros.
+ If an error is returned by <B>waddch</B> (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
+ <B>waddch</B> where an error may be returned after successfully writing a
+ character to the lower-right corner of a window when <B>scrollok</B> is dis-
+ abled.
