NAME

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);

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 VALUES

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