Yes, it is not as straight forward with the weird VLC coding patterns.

You have pass a vlc_object_t pointer to vlc_thread_create(). This pointer is
then passed to the thread entry point. To pass custom data, you will
typically use the p_sys member from the vlc_object_t.

It implies that you actually "own" the vlc_object_t, as modifying someone
else's object p_sys pointer is more than likely to cause a crash.
