NAME

       syslog.h - definitions for system error logging

SYNOPSIS

       #include <syslog.h>

DESCRIPTION

       The  <syslog.h>  header shall define the following symbolic constants, zero or more of which may be OR'ed
       together to form the logopt option of openlog():

       LOG_PID
              Log the process ID with each message.

       LOG_CONS
              Log to the system console on error.

       LOG_NDELAY
              Connect to syslog daemon immediately.

       LOG_ODELAY
              Delay open until syslog() is called.

       LOG_NOWAIT
              Do not wait for child processes.

       The following symbolic constants shall be  defined  as  possible  values  of  the  facility  argument  to
       openlog():

       LOG_KERN
              Reserved for message generated by the system.

       LOG_USER
              Message generated by a process.

       LOG_MAIL
              Reserved for message generated by mail system.

       LOG_NEWS
              Reserved for message generated by news system.

       LOG_UUCP
              Reserved for message generated by UUCP system.

       LOG_DAEMON
              Reserved for message generated by system daemon.

       LOG_AUTH
              Reserved for message generated by authorization daemon.

       LOG_CRON
              Reserved for message generated by clock daemon.

       LOG_LPR
              Reserved for message generated by printer system.

       LOG_LOCAL0
              Reserved for local use.

       LOG_LOCAL1
              Reserved for local use.

       LOG_LOCAL2
              Reserved for local use.

       LOG_LOCAL3
              Reserved for local use.

       LOG_LOCAL4
              Reserved for local use.

       LOG_LOCAL5
              Reserved for local use.

       LOG_LOCAL6

       LOG_LOCAL7
              Reserved for local use.

       The  following  shall  be  declared  as macros for constructing the maskpri argument to setlogmask(). The
       following macros expand to an expression of type int when the argument pri is an expression of type int:

       LOG_MASK(pri)
              A mask for priority pri.

       The following constants shall be defined as possible values for the priority argument of syslog():

       LOG_EMERG
              A panic condition was reported to all processes.

       LOG_ALERT
              A condition that should be corrected immediately.

       LOG_CRIT
              A critical condition.

       LOG_ERR
              An error message.

       LOG_WARNING
              A warning message.

       LOG_NOTICE
              A condition requiring special handling.

       LOG_INFO
              A general information message.

       LOG_DEBUG
              A message useful for debugging programs.

       The following shall be declared as functions and may also be defined as macros. Function prototypes shall
       be provided.

              void  closelog(void);
              void  openlog(const char *, int, int);
              int   setlogmask(int);
              void  syslog(int, const char *, ...);
