◆ block_plugin_set_test_check_query()

static enum GNUNET_GenericReturnValue block_plugin_set_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
clsclosure
typeblock type
queryoriginal query (hash)
xqueryextrended query data (can be NULL, depending on type)
xquery_sizenumber of bytes in xquery
Returns
GNUNET_OK if the query is fine, GNUNET_NO if not

Function called to validate a block for storage.

Parameters
clsclosure

blockblock data to validate
block_sizenumber of bytes in block
Returns
GNUNET_OK if the block is fine, GNUNET_NO if not

)
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
clsclosure
typeblock type
groupwhich block group to use for evaluation
queryoriginal query (hash)
xqueryextrended query data (can be NULL, depending on type)
xquery_sizenumber of bytes in xquery
reply_blockresponse to validate
reply_block_sizenumber of bytes in reply_block
Returns
characterization of result

@ GNUNET_BLOCK_REPLY_OK_MORE
Valid result, and there may be more.
#define GNUNET_assert(cond)
Use this for fatal errors that cannot be handled.

◆ block_plugin_set_test_get_key()

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
clsclosure
typeblock type
blockblock to get the key for
block_sizenumber of bytes in block
keyset 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)
