ConfigureAndWatch

[Donevan Dolby <do...@base2s.com>]

All,

I have recently inherited a project that is using log4cxx and one thing I
want to change is to dynamically change the logging level as the
application is running.  This looks like it should be possible
using DOMConfigurator::configureAndWatch("./log4cxx.xml", 1000); which
should check the log file every second to see if it has changed.  If i
change the logging level in the file and save it out it has no affect on my
logs, however, if I restart it takes the new settings.  I have attached to
the running application and see no watchdog thread that would be checking
if the file has been updated.  Any help would be appreciated

The watchdog thread will disappear after fork() or daemon(). Should 
configureAndWatch() after fork().
