Re: [boost] [Logging] logger as class's member

I'm not sure you can do (string)"A.". Try ::createlog(string("A.") + get_name());

I am sorry not describle the question clearly. the function ::createlog is just in my mind not on code (the author of logging not privide) I just want (really want) there will be such a function can solve my problem! so, Is there any other way to my goal ?
