 *  \defgroup Output Output Interface

 *

 *  The output functions present an interface similar to the stdio functions

 *  on top of different underlying output destinations.

 *

 *  Many PCM debugging functions (\c snd_pcm_xxx_dump_xxx) use such an output

 *  handle to be able to write not only to the screen but also to other

 *  destinations, e.g. to files or to memory buffers.
