typedef struct __db_env DB_ENV;
The DB_ENV object is the handle for a Berkeley DB environment -- a
collection including support for some or all of caching, locking,
logging and transaction subsystems, as well as databases and log files.
Methods off the DB_ENV handle are used to configure the
environment as well as to operate on subsystems and databases in the
DB_ENV handles are free-threaded if the DB_THREAD flag
is specified to the DB_ENV->open method when the environment is opened.
The DB_ENV handle should not be closed while any other handle
remains open that is using it as a reference (for example, DB
or DB_TXN). Once either the DB_ENV->close or
DB_ENV->remove methods are called, the handle may not be accessed again,
regardless of the method's return.
