int copywin(const WINDOW *srcwin, WINDOW *dstwin, int sminrow, int smincol,
int dminrow, int dmincol, int dmaxrow, int dmaxcol, int overlay);
Is a pointer to the source window to be copied.
Is a pointer to the destination window to be overlayed or overwritten.
Is the row coordinate of the upper left corner of the rectangular area on the source window to be copied.
Is the column coordinate of the upper left corner of the rectangular area on the source window to be copied.
Is the row coordinate of the upper left corner of the rectangular area on the destination window to be overlayed or overwritten.
Is the column coordinate of the upper left corner of the rectangular area on destination window to be overlayed or overwritten.
Is the row coordinate of the lower right corner of the rectangular area on the destination window to be overlayed or overwritten.
Is the column coordinate of the lower right corner of the rectangular area on the destination window to be overlayed or overwritten.
Is a TRUE or FALSE value that determines whether the destination window is overlayed or overwritten.
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().
Upon successful completion, the copywin() function returns OK. Otherwise, it returns ERR.
No errors are defined.
