Hi again,

well i have found some anwers to my questions on the document. I'll come back later on.

How a log record is recognized, i.e. I don't see std::endl neither std::flush are used in the examples. How many lines result in the following example if condifiton is true (2 or 3)

    src::logger_mt& lg = my_logger::get();
    if (lg.open_record()) {
        lg.strm() << "Hello ";
        lg.strm() << "world!";
    }
    // do something
    if (condition) {
        if (lg.open_record()) lg.strm() << "Bye!";
    }

Can other logs be interleaved between "Hello " , "world!"  and Bye in a multi threaded program? 

Thanks,
Vicente
