// Typemaps for wxInputStream
//
// We assume that input params taking a wxInputStream& will *not* take
// ownership of the stream and so we manage it in the typemaps. On the other
// hand, when a paramter expects a wxInputStream* then it does take ownership
// (such as wxFSFile) and so the typemap will make a copy of the stream object
// to give to it.
