| | curs_overlay, overlay, overwrite, copywin - overlap and manipulate overlapped curses windows |
SYNOPSIS
| |
cc [ flag ... ] file ... -lcurses [ library ... ]
#include <curses.h> int overlay(WINDOW *srcwin, WINDOW *dstwin); |
| | int overwrite(WINDOW *srcwin, WINDOW *dstwin); |
| | int copywin(WINDOW *srcwin, WINDOW *dstwin, int sminrow, int smincol, int dminrow, int dmincol, int dmaxrow, int dmaxcol, int overlay); |
| |
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().

Routines that return an integer return ERR upon failure and an integer value other than ERR upon successful completion.

The header <curses.h> automatically includes the headers <stdio.h> and <unctrl.h>.
Note that overlay() and overwrite may be macros.
