* \defgroup Input Input Interface
* The input functions present an interface similar to the stdio functions
* on top of different underlying input sources.
* The #snd_config_load function uses such an input handle to be able to
* load configurations not only from standard files but also from other
* sources, e.g. from memory buffers.

* \brief Internal structure for an input object.
* The ALSA library uses a pointer to this structure as a handle to an
* input object. Applications don't access its contents directly.
