title: Is Log4cplus RollingFileAppender Asynchronous or not
body: <p>I'm going to add Log4cplus for our application. Our application is written in C++ and it is multithreaded. I want to use the Log4Cplus RollingFileAppender for the same.</p>
  
  <p>I know Log4Cplus was derived from Java Log4j. As I didn't know Java well, I have no idea on Log4j. </p>
  
  <p>My questions are as follows,</p>
  
  <ol>
  <li>Is Log4Cplus RollingFileAppender asynchronous or not ?. Then what is the use of AsyncAppender ?</li>
  <li>Is RollingFileAppender thread safe ?</li>
  <li>Do I need to handle code for thread safety with RollingFileAppender or is it inbuilt ?</li>
  </ol>
  
  <p>Also can some one point me some examples for multi threaded rollingfileappender ?</p>
