A trailing newline is added if + necessary. Each message is tagged with a priority composed of a *facility* and + a *level*. The optional *priority* argument, which defaults to + :const:`LOG_INFO`, determines the message priority. If the facility is not + encoded in *priority* using logical-or (``LOG_INFO | LOG_USER``), the value + given in the :func:`openlog` call is used. + + +.. function:: openlog(ident[, logopt[, facility]]) + + Logging options other than the defaults can be set by explicitly opening the log + file with :func:`openlog` prior to calling :func:`syslog`. The defaults are + (usually) *ident* = ``'syslog'``, *logopt* = ``0``, *facility* = + :const:`LOG_USER`. The *ident* argument is a string which is prepended to every + message. The optional *logopt* argument is a bit field - see below for possible + values to combine. The optional *facility* argument sets the default facility + for messages which do not have a facility explicitly encoded. + + +.. function:: closelog() + + Close the log file. + + +.. function:: setlogmask(maskpri) + + Set the priority mask to *maskpri* and return the previous mask value. Calls to + :func:`syslog` with a priority level not set in *maskpri* are ignored. The + default is to log all priorities. The function ``LOG_MASK(pri)`` calculates the + mask for the individual priority *pri*. The function ``LOG_UPTO(pri)`` + calculates the mask for all priorities up to and including *pri*. + +The module defines the following constants: + +Priority levels (high to low): + :const:`LOG_EMERG`, :const:`LOG_ALERT`, :const:`LOG_CRIT`, :const:`LOG_ERR`, + :const:`LOG_WARNING`, :const:`LOG_NOTICE`, :const:`LOG_INFO`, + :const:`LOG_DEBUG`. + +Facilities: + :const:`LOG_KERN`, :const:`LOG_USER`, :const:`LOG_MAIL`, :const:`LOG_DAEMON`, + :const:`LOG_AUTH`, :const:`LOG_LPR`, :const:`LOG_NEWS`, :const:`LOG_UUCP`, + :const:`LOG_CRON` and :const:`LOG_LOCAL0` to :const:`LOG_LOCAL7`. + +Log options: + :const:`LOG_PID`, :const:`LOG_CONS`, :const:`LOG_NDELAY`, :const:`LOG_NOWAIT` + and :const:`LOG_PERROR` if defined in ``<syslog.h>``. + |
