◆ dt_pixelpipe_cache_pressure_monitor_init()

void dt_pixelpipe_cache_pressure_monitor_init	(	dt_pixelpipe_cache_pressure_monitor_t *	m,
		size_t	plan
	)

A monitor for a cache planned at plan bytes: full budget, nothing measured, no watcher.

size_t dt_pixelpipe_cache_pressure_react	(	dt_pixelpipe_cache_pressure_monitor_t *	m,
		const dt_pixelpipe_cache_pressure_sink_t *	sink
	)

Close the window since the last measurement and act on it: shed past the threshold, let the budget climb back under it, do nothing in between. Returns the bytes shed.
