$ident
   , int $option
   , int $facility
   )openlog() opens a connection to the system logger for a program.
 
   The use of openlog() is optional. It
   will automatically be called by syslog() if
   necessary, in which case ident will default
   to FALSE.
  
ident
       The string ident is added to each message. 
      
option
       The option argument is used to indicate
       what logging options will be used when generating a log message.
