DESCRIPTION
The RoarAudio VIO interface is RoarAudio's IO abstraction layer. It provides basic IO functions such as read and write independing on the
underlaying IO. For Example can you open a plain or a gziped file via the VIO layer. After a successful open both objects behave the same,
libroar takes care about the compression in the gzip case.
