<p>Apache2::MPM - Perl API for accessing Apache MPM information</p>
<h1 id="Synopsis">Synopsis</h1>
<pre><code> use Apache2::MPM ();
# check whether Apache MPM is threaded
if (Apache2::MPM->is_threaded) { do_something() }
# which mpm is used
my $mpm = lc Apache2::MPM->show;

<h1 id="Description">Description</h1>
<p><code>Apache2::MPM</code> provides the Perl API for accessing Apache MPM information.</p>
<h1 id="API">API</h1>
<p><code>Apache2::MPM</code> provides the following functions and/or methods:</p>
<h2 id="query"><code>query</code></h2>
<p>Query various attributes of the MPM</p>
<pre><code> my $query = Apache2::MPM->query($const);</code></pre>
<dl>
<dt id="obj:-class-Apache2::MPM-class">obj: <code>$class</code> ( <code><a>Apache2::MPM class</a></code> )</dt>
<dd>
<p>the class name</p>
</dd>
<dt id="arg1:-const-Apache2::Const-:mpmq-group-constant">arg1: <code>$const</code> ( <code><a>Apache2::Const :mpmq group constant</a></code> )</dt>
<dd>
<p>The MPM attribute to query.</p>
</dd>
<dt id="ret:-query-boolean">ret: <code>$query</code> ( boolean )</dt>
<dd>
<p>the result of the query</p>
</dd>
<dt id="since:-2.0.00">since: 2.0.00</dt>
<dd>
</dd>
</dl>
<p>For example to test whether the mpm is static:</p>
<pre><code> use Apache2::Const -compile => qw(MPMQ_STATIC);
if (Apache2::MPM->query(Apache2::Const::MPMQ_STATIC)) { ... }</code></pre>
<h2 id="is_threaded"><code>is_threaded</code></h2>
<p>Check whether the running Apache MPM is threaded.</p>
<pre><code> my $is_threaded = Apache2::MPM->is_threaded;</code></pre>
<dl>
<dt id="obj:-class-Apache2::MPM-class1">obj: <code>$class</code> ( <code><a>Apache2::MPM class</a></code> )</dt>
<dd>
<p>the class name</p>
</dd>
<dt id="ret:-is_threaded-boolean">ret: <code>$is_threaded</code> ( boolean )</dt>
<dd>
<p>threaded or not</p>
</dd>
<dt id="since:-2.0.001">since: 2.0.00</dt>
<dd>
</dd>
</dl>
<p>Note that this functionality is just a shortcut for:</p>
<pre><code> use Apache2::Const -compile => qw(MPMQ_IS_THREADED);
my $is_threaded = Apache2::MPM->query(Apache2::Const::MPMQ_IS_THREADED);</code></pre>
<h2 id="show"><code>show</code></h2>
<p>What mpm is used</p>
<pre><code> my $mpm = Apache2::MPM->show();</code></pre>
<dl>
<dt id="obj:-class-Apache2::MPM-class2">obj: <code>$class</code> ( <code><a>Apache2::MPM class</a></code> )</dt>
<dd>
<p>the class name</p>
</dd>
<dt id="ret:-mpm-string">ret: <code>$mpm</code> ( string )</dt>
<dd>
<p>the name of the MPM. e.g., "Prefork".</p>
</dd>
<dt id="since:-2.0.002">since: 2.0.00</dt>
<dd>
</dd>
