NAME
     mvderwin - define window coordinate transformation

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

     #include <curses.h>

     int mvderwin(WINDOW *win, int pary, int parx);

DESCRIPTION
     The mvderwin() function specifies a mapping of characters. The func-
     tion identifies a mapped area of the parent of the specified window,
     whose size is the same as the size of the specified window and whose
     origin is at (pary, parx) of the parent window.

     -  During any refresh of the specified window, the characters
        displayed in that window's display area of the terminal are taken
        from the mapped area.

     -  Any references to characters in the specified window obtain or
        modify characters in the mapped area.

     That is, mvderwin() defines a coordinate transformation from each
     position in the mapped area to a corresponding position (same y, x
     offset from the origin) in the specified window.

RETURN VALUE
     Upon successful completion, mvderwin() returns OK. Otherwise, it
     returns ERR.

ERRORS
     No errors are defined.
