cdef :put, VOID, db: VOIDP, options: VOIDP, key: VOIDP, keylen: ULONG, val: VOIDP, vallen: ULONG, errptr: VOIDP
cdef :get, VOIDP, db: VOIDP, options: VOIDP, key: VOIDP, keylen: ULONG, vallen: VOIDP, errptr: VOIDP
cdef :delete, VOID, db: VOIDP, options: VOIDP, key: VOIDP, keylen: ULONG, errptr: VOIDP

options = C.struct ['char c', 'long n']
db = C.open options, './path', errors
db.free = C[:release_db]
C.put db, 'a', 1 ...
