Function Documentation

dt_pixelpipe_cache_alloc_align_cache_impl()

void * dt_pixelpipe_cache_alloc_align_cache_impl	(	size_t	size,
		int	id,
		const char *	name
	)

Allocate aligned memory tracked by the pixelpipe cache. This allows LRU cache entries to be evicted if needed to make room.

Parameters

cache	Pixelpipe cache to manage.
size	Buffer size in bytes.
id	Pipeline type owning the buffer.
name	Human-readable name.

Returns

void* Pointer to the allocated buffer, or NULL on failure.
