Macros
#define	GNUNET_DATASTORE_MAX_VALUE_SIZE 65536
	Maximum size of a value that can be stored in the datastore.

Typedefs
typedef void(*	GNUNET_DATASTORE_ContinuationWithStatus) (void cls, int32_t success, struct GNUNET_TIME_Absolute min_expiration, const char msg)
	Continuation called to notify client about result of the operation.

typedef void(*	GNUNET_DATASTORE_DatumProcessor) (void cls, const struct GNUNET_HashCode key, size_t size, const void *data, enum GNUNET_BLOCK_Type type, uint32_t priority, uint32_t anonymity, uint32_t replication, struct GNUNET_TIME_Absolute expiration, uint64_t uid)
	Process a datum that was stored in the datastore.

Functions
struct GNUNET_DATASTORE_Handle *	GNUNET_DATASTORE_connect (const struct GNUNET_CONFIGURATION_Handle *cfg)
	Connect to the datastore service.

void	GNUNET_DATASTORE_disconnect (struct GNUNET_DATASTORE_Handle *h, int drop)
	Disconnect from the datastore service (and free associated resources).

	Reserve space in the datastore.

struct GNUNET_DATASTORE_QueueEntry *	GNUNET_DATASTORE_put (struct GNUNET_DATASTORE_Handle h, uint32_t rid, const struct GNUNET_HashCode key, size_t size, const void data, enum GNUNET_BLOCK_Type type, uint32_t priority, uint32_t anonymity, uint32_t replication, struct GNUNET_TIME_Absolute expiration, unsigned int queue_priority, unsigned int max_queue_size, GNUNET_DATASTORE_ContinuationWithStatus cont, void cont_cls)
	Store an item in the datastore.

	Signal that all of the data for which a reservation was made has been stored and that whatever excess space might have been reserved can now be released.

struct GNUNET_DATASTORE_QueueEntry *	GNUNET_DATASTORE_remove (struct GNUNET_DATASTORE_Handle h, const struct GNUNET_HashCode key, size_t size, const void data, unsigned int queue_priority, unsigned int max_queue_size, GNUNET_DATASTORE_ContinuationWithStatus cont, void cont_cls)
	Explicitly remove some content from the database.

struct GNUNET_DATASTORE_QueueEntry *	GNUNET_DATASTORE_get_key (struct GNUNET_DATASTORE_Handle h, uint64_t next_uid, bool random, const struct GNUNET_HashCode key, enum GNUNET_BLOCK_Type type, unsigned int queue_priority, unsigned int max_queue_size, GNUNET_DATASTORE_DatumProcessor proc, void *proc_cls)
	Get a result for a particular key from the datastore.

struct GNUNET_DATASTORE_QueueEntry *	GNUNET_DATASTORE_get_zero_anonymity (struct GNUNET_DATASTORE_Handle h, uint64_t next_uid, unsigned int queue_priority, unsigned int max_queue_size, enum GNUNET_BLOCK_Type type, GNUNET_DATASTORE_DatumProcessor proc, void proc_cls)

void	GNUNET_DATASTORE_cancel (struct GNUNET_DATASTORE_QueueEntry *qe)
	Cancel a datastore operation.
