Remove cache lines matching id. Entries locked in read/write or having reference count greater than 0 are not removed.

Parameters

id	ID of the pipeline owning the cache line, or -1 to remove all lines.

		const char *	name,
		const int	id,
		void **	data,
		struct dt_iop_buffer_dsc_t **	dsc,
		struct dt_pixel_cache_entry_t **	entry
	)

Get a cache line from the cache.

WARNING: This internally increases the reference count, so you have to manually decrease it using dt_dev_pixelpipe_ref_count_entry() once the cache line content has been consumed or it will never be freed.

WARNING: if the cache line was newly allocated, a write lock is put on straight away. You will have to release it from the same calling thread next, to avoid dead locks.

Parameters

cache
hash	State checksum of the cache line.
size	Buffer size in bytes.
name	Name of the cache line (for debugging).
id	ID of the pipeline owning the cache line.
data	Pointer to the buffer pointer (returned).
dsc	Pointer to the buffer descriptor (returned).
cache_entry	a reference to the cache entry, to be reused later. Can be NULL. The caller doesn't own the data and shouldn't free it.

Returns

int 1 if the cache line was freshly allocated, 0 if it was found in the cache.

dt_pixel_cache_entry_t * dt_dev_pixelpipe_cache_get_entry	(	dt_dev_pixelpipe_cache_t *	cache,

	)

Return a reference to the cache entry holding the data buffer, or NULL if not found.

WARNING: this immediately puts a read lock on the entry cache, if found. You will need to manually release it later with dt_dev_pixelpipe_cache_rdlock_entry() or you will get a deadlock and this entry will never be deleted.

Get an existing cache line from the cache. This is similar to dt_dev_pixelpipe_cache_get, but it does not create a new cache line if it is not found.
