  * This function asks NetEQ for more speech/audio data.
  *
  * Input:
- *		- inst			: NetEQ instance, i.e. the user that requests more 
- *						  speech/audio data.
- *		- outdata		: Pointer to a memory space where the output data
- *						  should be stored.
- *      - BGNonly       : If non-zero, RecOut will only produce background
- *                        noise. It will still draw packets from the packet
- *                        buffer, but they will never be decoded.
