NAME

mvderwin — define window coordinate transformation

SYNOPSIS

#include <curses.h>

int mvderwin(WINDOW *win, int par_y, int par_x);

DESCRIPTION

The mvderwin() function specifies a mapping of characters.  The function 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 (par_y, par_x) 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.
