DbEnv::log_flush

APIRef

#include <db_cxx.h>

int DbEnv::log_flush(const DbLsn *lsn);

Description

The DbEnv::log_flush method guarantees that all log records whose DbLsn values are less than or equal to the lsn argument have been written to disk. If lsn is NULL, all records in the log are flushed.

The DbEnv::log_flush method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.

Errors

If a fatal error occurs in Berkeley DB, the DbEnv::log_flush method will fail and either return DB_RUNRECOVERY or throw an exception encapsulating DB_RUNRECOVERY, at which point all subsequent database calls will fail in the same way.

In addition, the DbEnv::log_flush method may fail and throw an exception or return a non-zero error for the following conditions:

EINVAL
An invalid flag value or parameter was specified.

In addition, the DbEnv::log_flush method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods.
