The <STRONG>overlay</STRONG> and <STRONG>overwrite</STRONG> routines overlay <EM>srcwin</EM> on top
of <EM>dstwin</EM>. <EM>scrwin</EM> and <EM>dstwin</EM> are not required to be the
same size; only text where the two windows overlap is
copied. The difference is that <STRONG>overlay</STRONG> is non-destructive
(blanks are not copied) whereas <STRONG>overwrite</STRONG> is destructive.
+
+</PRE><H3><a name="h3-copywin">copywin</a></H3><PRE>
The <STRONG>copywin</STRONG> routine provides a finer granularity of con-
- trol over the <STRONG>overlay</STRONG> and <STRONG>overwrite</STRONG> routines. Like in the
+ trol over the <STRONG>overlay</STRONG> and <STRONG>overwrite</STRONG> routines. As in the
<STRONG>prefresh</STRONG> routine, a rectangle is specified in the destina-
tion window, (<EM>dminrow</EM>, <EM>dmincol</EM>) and (<EM>dmaxrow</EM>, <EM>dmaxcol</EM>),
and the upper-left-corner coordinates of the source win-
then copying is non-destructive, as in <STRONG>overlay</STRONG>.

-<H2>RETURN VALUE</H2><PRE>

Routines that return an integer return <STRONG>ERR</STRONG> upon failure,
and <STRONG>OK</STRONG> (SVr4 only specifies "an integer value other than
<STRONG>ERR</STRONG>") upon successful completion.
the window would be placed off-screen.

The XSI Curses standard, Issue 4 describes these functions
(adding the const qualifiers). It further specifies their
behavior in the presence of characters with multibyte ren-
ditions (not yet supported in this implementation).
