* Prototype for the @a timebase_callback used to provide extended
* position information. Its output affects all of the following
* process cycle. This realtime function must not wait.
*
* This function is called immediately after process() in the same
* thread whenever the transport is rolling, or when any client has
* requested a new position in the previous cycle. The first cycle
* after jack_set_timebase_callback() is also treated as a new
* position, or the first cycle after jack_activate() if the client
* had been inactive.
*
* The timebase master may not use its @a pos argument to set @a
* pos->frame. To change position, use jack_transport_reposition() or
* jack_transport_locate(). These functions are realtime-safe, the @a
* timebase_callback can call them directly.
*
* @param state current transport state.
* @param nframes number of frames in current period.
* @param pos address of the position structure for the next cycle; @a
* pos->frame will be its frame number. If @a new_pos is FALSE, this
* structure contains extended position information from the current
* cycle. If TRUE, it contains whatever was set by the requester.
* The @a timebase_callback's task is to update the extended
* information here.
* @param new_pos TRUE (non-zero) for a newly requested @a pos, or for
* the first cycle after the @a timebase_callback is defined.
* @param arg the argument supplied by jack_set_timebase_callback().
