Return the latest raw timing data structure. The returned pointer
* refers to an internal read-only instance of the timing
* structure. The user should make a copy of this structure if
* wanting to modify it. An in-place update to this data structure
* may be requested using pa_stream_update_timing_info().
*
* If no timing information has been received before (i.e. by
* requesting pa_stream_update_timing_info() or by using
* PA_STREAM_AUTO_TIMING_UPDATE), this function will return NULL.
*
* Please note that the write_index member field (and only this field)
* is updated on each pa_stream_write() call, not just when a timing
* update has been received.
