syslog(3C) syslog(3C)
LOG_NOWAIT Do not wait for children forked to log messages on the console.
This option should be used by processes that enable notification
of child termination via SIGCLD, because syslog()
might
otherwise block, waiting for a child whose exit status has already
been collected.
facility encodes a default facility to be assigned to all messages written subsequently by
syslog() with no explicit facility encoded.
LOG_KERN Messages generated by the kernel. These cannot be generated
by any user processes.
LOG_USER Messages generated by random user processes. This is the
default facility identifier if none is specified.
LOG_MAIL The mail system.
LOG_DAEMON System daemons, such as inetd(1M), ftpd(1M), etc.
LOG_AUTH The authorization system: login(1), su(1), getty(1M), etc.
LOG_SYSLOG Messages generated internally by syslogd daemon.
LOG_LPR The line printer spooling system: lp(1), lpsched(1M), etc.
LOG_NEWS Messages generated by the news system.
LOG_UUCP Messages generated by the UUCP system.
LOG_CRON Messages generated by the CRON daemon.
LOG_LOCAL0 Reserved for local use. Similarly for LOG_LOCAL1 through
LOG_LOCAL7 .
facility and level uses an encoded code for logging in syslogd message. The encoded code
for facility and level are as follows.
LOG_KERN A LOG_EMERG 0
LOG_USER B LOG_ALERT 1
LOG_MAIL C LOG_CRIT 2
LOG_DAEMON D LOG_ERR 3
LOG_AUTH E LOG_WARNING 4
LOG_SYSLOG F LOG_NOTICE 5
LOG_LPR G LOG_INFO 6
LOG_NEWS H LOG_DEBUG 7
LOG_UUCP I
LOG_CRON J
LOCAL0-7 Q-X
closelog()
closes the log file.
setlogmask()
sets the log priority mask to maskpri and returns the previous mask. Calls to syslog()
with a priority not set in maskpri are rejected. The mask for an individual priority pri is
calculated by the macro LOG_MASK( pri); the mask for all priorities up to and including
toppri is given by the macro LOG_UPTO(toppri). By default, all priorities are logged.
ERRORS
syslog fails if any of the following conditions are encountered:
[EAGAIN] The named pipe /dev/log is blocked for writing.
[ENOENT] The named pipe /dev/log bold) could not be opened successfully.
