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: copywin, overlay, overwrite: XCURSES4.2 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. SEE ALSO
Functions: curses(3), curs_pad(3), curs_refresh(3) Others: standards(5) curs_overlay(3)
