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

LIBRARY
       Curses Library (libcurses)

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

DESCRIPTION
       The  overlay  and  overwrite  routines  overlay srcwin on top of dstwin.  The scrwin and dstwin parameters do not have to be the same size;
       Curses copies only the text in the region where the two windows overlap. The difference between the routines is that overlay is nondestruc-
       tive (blanks are not copied), whereas overwrite is destructive.

       The  copywin  routine provides a finer granularity of control over the same operation performed by overlay and overwrite. Like the prefresh
       routine, copywin specifies a rectangle in the destination window, (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 nondestructive, as is the case for
       the overlay function.

NOTES
       The header file <curses.h> automatically includes the header file <stdio.h>.

RETURN VALUES
       These routines return ERR upon failure and OK upon successful completion.
