Subject Re: How to clean up the log4cxx objects to avoid the memory leak?
Date Wed, 14 Oct 2009 08:20:49 GMT
Thanks, Deepak

So if want to close one created looger and release its releated resources,
what should I do? using smart pointer, I don't need to delete the objects.
But How can I release the resources? Do I need to call the below API to
release the resources?

//close the appender
_appenderPtr->close();

//close all appenders associated with the logger
_loggerPtr->closeNestedAppenders();
_loggerPtr->removeAllAppenders();

Or some other APIs I need to call to release all resources to avoid memory
leak?

Thank you.
