Detailed Description

A data structure which approximates a least recently used (LRU) cache.

Implemented as a basic randomized hash table.

Function Documentation

void* lru_cache_find	(	lru_cache *	ht,
		const void *	index,
		uint32_t	index_len
	)

XXX: finish documenting.

Returns:

A pointer to data previously stored at index. If no data was found at index, NULL is returned.

bool lru_cache_remove	(	lru_cache *	ht,
		const void *	index,
		uint32_t	index_len
	)

XXX: finish documenting.

Removes entry from table at index.

Returns:

A pointer to data that was there previously or NULL if no entry is at index.
