storing the logs

hi , my module produces some data (very cititcal) and that i want to log that to some disk residing file like log files. So among several ways like using syslog (and family) ,audit daemon i am not finding the way to use the functionalities of any of these subsystems .i mean : practically i am still unable to do that. can someone point me to some practical implementations used by some other modules or some practically sound articles to achieve this? thanks a lot in advance. -- ........................ *MOHIT VERMA*
