[pjsip] how to disable buffering in pjsua log file in linux?

If I recall correctly, log file writing is done via stdio and there is
no way in pjsip to configure buffering. There is a commented out line
that flushes the logfile with an advisory not to enable because of the
performance hit. It's obviously not a good idea to flush on every log
entry. It would be pretty easy to run a periodic timer task that flushes
the logfile a few times a second, that may suffice for your needs.

Not sure why you see different behavior on Windows, in my experience the
pjsip log is buffered on all platforms.

I am trying pjsua 2.0 in linux (ubuntu 64 LTS) and I am experienced
that the writing of log file is highly buffered. I need to detect
events in real time from log, and due to this, I have delays for more
than 10 seconds and even uncompleted lines ...
making a "tail -f logfile" can show this easily
In windows the log events are written inmediatly so I can use realtime
events from log files-
Anybody can help me with this? Are there some config parameter in
headers (may be something like PJ_LOG_USE_STACK_BUFFER) to chage this
behaviour in linux?
Anybody know if pjsua 2.6 has better log realtime writting (I have
some patches in 2.0 and I dont want to rewrite again)
And one more... what about OSX?
Thanks again for this amazing software...
