win

Is a pointer to the window to be mapped.

par_y

Is the y (row) coordinate of the placement of the upper left corner of window relative to the parent window.

par_x

Is the x (column) coordinate of the placement of the upper left corner of the window relative to the parent window.

The mvderwin() function defines a mapped area of win's parent window that is the same size as win and has its upper left corner at position par_y, par_x of the parent window.

Whenever win is refreshed, its contents are updated to match those of the mapped area and any reference to characters in win is treated as a reference to corresponding characters in the mapped area.

On success, the mvderwin() function returns OK. Otherwise, it returns ERR.

None.
