Re: question - php_stream_cast(...) and PHP_STREAM_AS_FD

If you're writing to a stream, you shouldn't use STREAM_MUST_SEEK, since it might give you a temporary stream that is not connected to the actual resource you opened; such a stream will be deleted when it is closed. Generally speaking, you should avoid using casting when possible; can you give more details about what you're opening (remote files?). Also, it looks like you are nesting streams--can I ask why? (it might be possible to do things a bit more cleanly). --Wez.
