<h1>Description</h1>
|
|
<p>The log_flush function guarantees that all log records whose
|
|
DB_LSN values
|
|
are less than or equal to the <b>lsn</b> argument have been
|
|
written to disk. If <b>lsn</b> is NULL, all records in the
|
|
log are flushed.
|
|
<p>The log_flush function returns a non-zero error value on failure and 0 on success.
|
|
<h1>Errors</h1>
|
|
<p>The log_flush function may fail and return a non-zero error for the following conditions:
|
|
<p><dl compact>
|
|
<p><dt>EINVAL<dd>An invalid flag value or parameter was specified.
|
|
</dl>
|
|
<p>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.
|
|
If a catastrophic error has occurred, the log_flush function may fail and return
|
|
<a href="../ref/program/errorret.html#DB_RUNRECOVERY">DB_RUNRECOVERY</a>, in which case all subsequent Berkeley DB calls will fail
|
|
in the same way.
