* This document describes the client API for the PulseAudio sound

* of applications and different needs in complexity:
- *
+ *
* \li The complete but somewhat complicated to use asynchronous API
* \li The simplified, easy to use, but limited synchronous API
*
* locale. Some functions will filter invalid sequences from the string, some
* will simply fail. To ensure reliable behaviour, make sure everything you
