X/Open Curses Library Functionscopywin(3XCURSES)


NAME

 copywin - overlay or overwrite any portion of 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);

PARAMETERS

 
srcwin
Is a pointer to the source window to be copied.
dstwin
Is a pointer to the destination window to be overlayed or overwritten.
sminrow
Is the row coordinate of the upper left corner of the rectangular area on the source window to be copied.
smincol
Is the column coordinate of the upper left corner of the rectangular area on the source window to be copied.
dminrow
Is the row coordinate of the upper left corner of the rectangular area on the destination window to be overlayed or overwritten.
dmincol
Is the column coordinate of the upper left corner of the rectangular area on destination window to be overlayed or overwritten.
dmaxrow
Is the row coordinate of the lower right corner of the rectangular area on the destination window to be overlayed or overwritten.
dmaxcol
Is the column coordinate of the lower right corner of the rectangular area on the destination window to be overlayed or overwritten.
overlay
Is a TRUE or FALSE value that determines whether the destination window is overlayed or overwritten.

DESCRIPTION

 

The copywin() function provides a finer granularity of control over the overlay(3XCURSES) and overwrite(3XCURSES) functions. As in the prefresh() function (see newpad(3XCURSES)), a rectangle is specified in the destination window, (dminrow, dmincol) and (dmaxrow, dmaxcol), and the upper-left-corner coordinates of the source window, (smincol, sminrow). If overlay is TRUE, then copying is non-destructive, as in overlay(). If overlay is FALSE, then copying is destructive, as in overwrite().

RETURN VALUES

 

Upon successful completion, the copywin() function returns OK. Otherwise, it returns ERR.

ERRORS

 

No errors are defined.
