Berkeley DB: DB_TXN->discard
DB_TXN->discard
|
 |
#include <db.h>
int
DB_TXN->discard(DB_TXN *tid, u_int32_t flags);
Description: DB_TXN->discard
The DB_TXN->discard method frees up all the per-process resources
associated with the specified DB_TXN handle, neither committing
nor aborting the transaction. This call may be used only after calls
to DB_ENV->txn_recover when there are multiple global transaction
managers recovering transactions in a single Berkeley DB environment. Any
transactions returned by DB_ENV->txn_recover that are not handled by
the current global transaction manager should be discarded using
DB_TXN->discard.
The DB_TXN->discard method
returns a non-zero error value on failure
and 0 on success.
After DB_TXN->discard has been called, regardless of its return, the
DB_TXN handle may not be accessed again.
Parameters
- flags
- The flags parameter is currently unused, and must be set to 0.
Errors
The DB_TXN->discard method
may fail and return one of the following non-zero errors:
- EINVAL
- If the transaction handle does not refer to a transaction that was
recovered into a prepared but not yet completed state; or if an
invalid flag value or parameter was specified.
Class
DB_ENV, DB_TXN
