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.
