Function Documentation

◆ block_plugin_setu_test_check_query()

static enum GNUNET_GenericReturnValue block_plugin_setu_test_check_query	(	void *	cls,
		enum GNUNET_BLOCK_Type	type,
		const struct GNUNET_HashCode *	query,
		const void *	xquery,
		size_t	xquery_size
	)

static

Function called to validate a query.

Parameters

cls	closure
ctx	block context
type	block type
query	original query (hash)
xquery	extrended query data (can be NULL, depending on type)
xquery_size	number of bytes in xquery

Returns: GNUNET_OK if the query is fine, GNUNET_NO if not

		enum GNUNET_BLOCK_Type	type,
		const void *	block,
		size_t	block_size
	)

static

Function called to validate a block for storage.

Parameters

cls	closure
type	block type
block	block data to validate
block_size	number of bytes in block

Returns: GNUNET_OK if the block is fine, GNUNET_NO if not

◆ block_plugin_setu_test_check_reply()

static enum GNUNET_BLOCK_ReplyEvaluationResult block_plugin_setu_test_check_reply	(	void *	cls,
		enum GNUNET_BLOCK_Type	type,
		struct GNUNET_BLOCK_Group *	group,
		const struct GNUNET_HashCode *	query,
		const void *	xquery,
		size_t	xquery_size,
		const void *	reply_block,
		size_t	reply_block_size
	)

static

Function called to validate a reply to a request.

Note that it is assumed that the reply has already been matched to the key (and signatures checked) as it would be done with the GetKeyFunction and the BlockEvaluationFunction.

Parameters

cls	closure
type	block type
group	which block group to use for evaluation
query	original query (hash)
xquery	extrended query data (can be NULL, depending on type)
xquery_size	number of bytes in xquery
reply_block	response to validate
reply_block_size	number of bytes in reply_block

Returns: characterization of result

		enum GNUNET_BLOCK_Type	type,
		const void *	block,
		size_t	block_size,
		struct GNUNET_HashCode *	key
	)

static

Function called to obtain the key for a block.

Parameters

cls	closure
type	block type
block	block to get the key for
block_size	number of bytes in block
key	set to the key (query) for the given block

Returns: GNUNET_OK on success, GNUNET_SYSERR if type not supported (or if extracting a key from a block of this type does not work)
