<h1>Description</h1>
<p>The log_register function registers a file name with the specified Berkeley DB
environment's log manager. The log manager records all file name mappings
at each checkpoint so that a recovery process can identify the file to
which a record in the log refers.
<p>The <b>dbp</b> argument should be a reference to the DB structure being
registered. The <b>name</b> argument should be a file name appropriate
for opening the file in the environment, during recovery.
<p>The log_register function returns a non-zero error value on failure and 0 on success.
<h1>Errors</h1>
<p>The log_register 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_register 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_register 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.
