NAME
       overlay, overwrite, copywin - overlay and manipulate overlapped curses windows

SYNOPSIS
       #include <curses.h>

       int overlay(const WINDOW *srcwin, WINDOW *dstwin);
       int overwrite(const WINDOW *srcwin, WINDOW *dstwin);
       int copywin(WINDOW *srcwin, WINDOW *dstwin, int sminrow,
	     int smincol, int dminrow, int dmincol, int dmaxrow,
	     int dmaxcol, int overlay);

DESCRIPTION
       The overlay and overwrite routines overlay srcwin on top of dstwin.  scrwin and dstwin are
       not required to be the same size; only text where the two windows overlap is copied.   The
       difference is that overlay is non-destructive (blanks are not copied) whereas overwrite is
       destructive.

       The copywin routine provides a finer granularity of control over the overlay and overwrite
       routines.   Like in the prefresh routine, a rectangle is specified in the destination win-
       dow, (dminrow, dmincol) and (dmaxrow, dmaxcol), and the upper-left-corner  coordinates  of
       the  source  window, (sminrow, smincol).  If the argument overlay is true, then copying is
       non-destructive, as in overlay.

RETURN VALUE
       Routines that return an integer return ERR upon failure, and OK (SVr4 only  specifies  "an
       integer value other than ERR") upon successful completion.

NOTES
       Note that overlay and overwrite may be macros.

PORTABILITY
       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  rendi-
       tions (not yet supported in this implementation).
