void(* GNUNET_NAMECACHE_BlockCallback)(void *cls, const struct GNUNET_GNSRECORD_Block *block)
Function called for matching blocks.
void * cls
Closure to pass to all plugin functions.
Information we have in an encrypted block with record data (i.e.
int(* cache_block)(void *cls, const struct GNUNET_GNSRECORD_Block *block)
Cache a block in the datastore.
int(* lookup_block)(void *cls, const struct GNUNET_HashCode *query, GNUNET_NAMECACHE_BlockCallback iter, void *iter_cls)
Get the block for a particular zone and label in the datastore.
A 512-bit hashcode.
struct returned by the initialization function of the plugin
