pump_cross()

void MayaFlux::Vruta::TaskScheduler::pump_cross ( DelayContext  context, ProcessingToken  clock_token, uint64_t  processing_units  )

private

Pump the MULTI_RATE list from one clock's context.

Called as a fall-through from process_token when the driving token is SAMPLE_ACCURATE or FRAME_ACCURATE. Reads the driving clock's position and offers each cross routine a resume under the given context. The CrossRoutine gate decides eligibility and claims the resume atomically, so both threads may call this concurrently on the same list.

Parameters

context	SAMPLE_BASED from the audio thread, FRAME_BASED from graphics.
clock_token	The token whose clock position drives this pump.
processing_units	Units to advance, matching the driving token's call.
