NAME
copywin — copy a region of a window
SYNOPSIS
#include <curses.h>
int copywin(const WINDOW *srcwin, WINDOW *dstwin, int sminrow,
int smincol, int dminrow, int dmincol, int dmaxrow,
int dmaxcol, int overlay);
DESCRIPTION
The
copywin()
function provides a finer granularity of control over the
overlay()
and
overwrite()
functions. As in the
prefresh()
function, 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 overlay is TRUE, then copying is non-destructive, as in
overlay().
If overlay is FALSE, then copying is destructive, as in
overwrite().
RETURN VALUE
Upon successful completion,
copywin()
returns OK. Otherwise, it returns ERR.
ERRORS
No errors are defined.
