#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
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.
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.
If a catastrophic error has occurred, the DbEnv::log_flush method may fail and either
return DB_RUNRECOVERY or throw an exception encapsulating
DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail
in the same way.
