<a name="AnjutaAsyncCommand.description"></a><h2>Description</h2>
<p><a class="link" href="AnjutaAsyncCommand.html" title="AnjutaAsyncCommand"><span class="type">AnjutaAsyncCommand</span></a> provides a simple way for plugins to run tasks that
are synchronous and usually take several seconds or longer to execute in
another thread so that such tasks do no block Anjuta's user interface.</p>
<p><a class="link" href="AnjutaAsyncCommand.html" title="AnjutaAsyncCommand"><span class="type">AnjutaAsyncCommand</span></a> automatically runs and manages the thread when the
command starts, and destroys it when the command finishes. Aside from
locking protected data with anjuta_async_command_lock/unlock, clients, and
even commands themselves need not even be concerned that their tasks are
rnning on another thread.</p>
<p>For an example of how <a class="link" href="AnjutaAsyncCommand.html" title="AnjutaAsyncCommand"><span class="type">AnjutaAsyncCommand</span></a> is used, see the Subversion plugin.</p>
