copywin(3X)                                                     copywin(3X)

NAME
     copywin - copy a region of a window

SYNOPSIS
     cc [flag ...] file ... -lcurses [library ...]

     #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() func-
     tion, 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.
