curs_overlay(3)						       curs_overlay(3)

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(const 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 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 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.

       X/Open defines no error conditions.  In this implementation, copywin,
       overlay and overwrite return an error if either of the window pointers
       are null, or if some part of the window would be placed off-screen.

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 renditions (not yet supported in this
       implementation).
