Detailed Description

Generic structure used for passing keys and data in and out of the database.

Values returned from the database are valid only until a subsequent update operation, or the end of the transaction. Do not modify or free them, they commonly point into the database itself.

Key sizes must be between 1 and mdb_env_get_maxkeysize() inclusive. The same applies to data sizes in databases with the MDB_DUPSORT flag. Other data items can in theory be from 0 to 0xffffffff bytes long.
