copywin - copy a region of a window
#include <curses.h> int copywin(const WINDOW *srcwin, WINDOW *dstwin, int sminrow, int smincol, int dminrow, int dmincol, int dmaxrow, int dmaxcol, int overlay);
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().
Upon successful completion, copywin() returns OK. Otherwise, it returns ERR.
No errors are defined.
