Type Definitions

The map library defines two data structures: MapElement and Map. A Binding is a pointer to a MapElement. A map element is a table of bindings, where each binding is given by the pair <external key, internal id>. An external key is a variable length byte string, which typically is constructed from various fields in a message header. An internal id is a fixed-sized identifier (e.g., a 32 or 64-bit memory address) which is a pointer to a protocol or session object.

				struct mapelement 		*next;

				void              		*externalkey;

				void              		*internalid;

		} MapElement, *Binding;

		typedef struct {

				int               		nEntries;

				int               		keySize;

				MapElement        		*cache;

				MapElement        		*freelist;

				MapElement        		**table;

				XkReturn          		(*resolve)();

				Binding           		(*bind)();

				XkReturn          		(*unbind)();

				XkReturn          		(*remove)();

		} *Map;
