# Cursor

The Cursor structure contains functions and structures to create and operate on cursors.

    structure Cursor:
      sig
        type HCURSOR and HINSTANCE
        type POINT = { x : int, y: int }
        type RECT =  { left: int, top: int, right: int, bottom: int }
        val hcursorNull : HCURSOR
        val isHcursorNull : HCURSOR -> bool
