The <STRONG>addch</STRONG>, <STRONG>waddch</STRONG>, <STRONG>mvaddch</STRONG> and <STRONG>mvwaddch</STRONG> routines put the
character <EM>ch</EM> into the given window at its current window
position, which is then advanced. They are analogous to
- <STRONG>putchar</STRONG> in <STRONG><A HREF="stdio.3.html">stdio(3)</A></STRONG>. If the advance is at the right mar-
+ <STRONG>putchar</STRONG> in <STRONG>stdio(3)</STRONG>. If the advance is at the right mar-
gin, the cursor automatically wraps to the beginning of
the next line. At the bottom of the current scrolling
region, if <STRONG>scrollok</STRONG> is enabled, the scrolling region is
other than <STRONG>ERR</STRONG>") upon successful completion, unless other-
wise noted in the preceding routine descriptions.
+ 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.
