- * SetCursor
- * setcurso.c
- *
- * This program demonstrates the use of the function SetCursor.
- * It sets the cursor shape to the cursor specified by hCursor. HCursor
- * is a handle to a cursor resource, which must have been loaded
- * previously using the LoadCursor function. The cursor is set only if the
- * new shape is different from the existing shape. If hCursor is NULL, the
- * cursor is removed from the screen. To change the cursor while it is in
- * a window, the class cursor for the given window's class must be set to
- * NULL. If the class cursor is not null, Windows restores the old shape
- * each time the mouse moves.
