Detailed Description

Macro Definition Documentation

   #define MDB_REVERSEKEY   0x02
       use reverse string keys

   #define MDB_DUPSORT   0x04
       use sorted duplicates

   #define MDB_INTEGERKEY   0x08
       numeric keys in native byte order: either unsigned int or size_t. The keys must all be of the same size.

   #define MDB_DUPFIXED   0x10
       with MDB_DUPSORT, sorted dup items have fixed size

   #define MDB_INTEGERDUP   0x20
       with MDB_DUPSORT, dups are MDB_INTEGERKEY-style integers

   #define MDB_REVERSEDUP   0x40
       with MDB_DUPSORT, use reverse string dups

   #define MDB_CREATE   0x40000
       create DB if not already existing
