| <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> |
