<h2>scoped_lock_d</h2>
|
|
<p>The <tt>scoped_lock_d</tt> directive constructs a parser that locks a mutex
|
|
during the attempt to match the contained parser.</p>
|
|
<p>Syntax:</p>
|
|
<pre> <span class="identifier">scoped_lock_d</span><span class="special">(</span>mutex<span class="special">&)[</span>body-parser<span class="special">]</span></pre>
|
|
<p>Note, that nesting <tt>scoped_lock_d</tt> directives bears the risk of deadlocks
|
|
since the order of locking depends on the grammar used and may even depend on
|
|
the input being parsed. Locking order has to be consistent within an application
|
|
to ensure deadlock free operation.</p>
