Also just to be clear, odp handles are opaque to the application and it does not have the right to set the handle to INVALID directly. It has to go through the implementation to INVALIDATE a handle and currently the only way is to call odp_xxx_destroy() API. Regards, Bala > > > Best regards. > > > > José. > > >
