<h3>Description: DbEnv::lock_id</h3>
<p>The DbEnv::lock_id method copies a locker ID, which is guaranteed to be
unique in the specified lock table, into the memory location to which
<b>idp</b> refers.</p>
<p>The <a href="../api_cxx/lock_id_free.html">DbEnv::lock_id_free</a> method should be called to return the locker ID to
the Berkeley DB library when it is no longer needed.</p>
<p>The DbEnv::lock_id 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.
</p>
<h3>Parameters</h3>
<dl compact>
<dt><b>idp</b><dd>The <b>idp</b> parameter references memory into which
the allocated locker ID is copied.
