<H2>DESCRIPTION</H2><PRE>
- The <B>overlay</B> and <B>overwrite</B> routines overlay <I>srcwin</I> on top
- of <I>dstwin</I>. <I>scrwin</I> and <I>dstwin</I> are not required to be the
- same size; only text where the two windows overlap is
- copied. The difference is that <B>overlay</B> is non-destructive
- (blanks are not copied) whereas <B>overwrite</B> is destructive.
+ 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.
- The <B>copywin</B> routine provides a finer granularity of con-
- trol over the <B>overlay</B> and <B>overwrite</B> routines. Like in the
- <B>prefresh</B> routine, a rectangle is specified in the destina-
- tion window, (<I>dminrow</I>, <I>dmincol</I>) and (<I>dmaxrow</I>, <I>dmaxcol</I>),
- and the upper-left-corner coordinates of the source win-
- dow, (<I>sminrow</I>, <I>smincol</I>). If the argument <I>overlay</I> is <B>true</B>,
- then copying is non-destructive, as in <B>overlay</B>.

<H2>RETURN VALUE</H2><PRE>
- Routines that return an integer return <B>ERR</B> upon failure,
- and <B>OK</B> (SVr4 only specifies "an integer value other than
- <B>ERR</B>") upon successful completion.

<H2>PORTABILITY</H2><PRE>
The XSI Curses standard, Issue 4 describes these functions
(adding the const qualifiers). It further specifies their
- behavior in the presence of characters with multi-byte
- renditions (not yet supported in this implementation).
