log_flush

APIRef

#include <db.h>

int log_flush(DB_ENV *env, const DB_LSN *lsn);

Description

The log_flush function guarantees that all log records whose DB_LSN 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 log_flush function returns a non-zero error value on failure and 0 on success.

Errors

If a fatal error occurs in Berkeley DB, the log_flush function will fail and return DB_RUNRECOVERY, at which point all subsequent database calls will fail in the same way.

In addition, the log_flush function may fail and return a non-zero error for the following conditions:

EINVAL
An invalid flag value or parameter was specified.

In addition, the log_flush function may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions.
