<p>APR::ThreadMutex - Perl API for APR thread mutexes</p>

<h1 id="Synopsis">Synopsis</h1>

<pre><code>  use APR::ThreadMutex ();

  my $mutex = APR::ThreadMutex-&gt;new($r-&gt;pool);
  $mutex-&gt;lock;
  $mutex-&gt;unlock;
  $mutex-&gt;trylock;</code></pre>

<h1 id="Description">Description</h1>

<p><code>APR::ThreadMutex</code> interfaces APR thread mutexes.</p>

<h1 id="API">API</h1>

<p><code>APR::ThreadMutex</code> provides the following functions and/or methods:</p>

<h1 id="Unsupported-API">Unsupported API</h1>

<p><code>APR::ThreadMutex</code> also provides auto-generated Perl interface for a few other methods which aren&#39;t tested at the moment and therefore their API is a subject to change. These methods will be finalized later as a need arises. If you want to rely on any of the following methods please contact the <a>the mod_perl development mailing list</a> so we can help each other take the steps necessary to shift the method to an officially supported API.</p>

<h2 id="DESTROY"><code>DESTROY</code></h2>

<p>META: Autogenerated - needs to be reviewed/completed</p>

<p>Destroy the mutex and free the memory associated with the lock.</p>

<pre><code>  $mutex-&gt;DESTROY();</code></pre>

<dl>

<dt id="obj:-mutex-APR::ThreadMutex-object">obj: <code>$mutex</code> ( <code><a>APR::ThreadMutex object</a></code> )</dt>

</dl>

<h2 id="lock"><code>lock</code></h2>

<p>META: Autogenerated - needs to be reviewed/completed</p>

<p>Acquire the lock for the given mutex. If the mutex is already locked, the current thread will be put to sleep until the lock becomes available.</p>

<h2 id="trylock"><code>trylock</code></h2>

<p>META: Autogenerated - needs to be reviewed/completed</p>

<p>Attempt to acquire the lock for the given mutex. If the mutex has already been acquired, the call returns immediately with APR_EBUSY. Note: it is important that the APR_STATUS_IS_EBUSY(s) macro be used to determine if the return value was APR_EBUSY, for portability reasons.</p>
