/* The option argument to openlog() is an OR of any of these:
|
|
*
|
|
* LOG_CONS - Write directly to system console if there is an error
|
|
* while sending to system logger.
|
|
* LOG_NDELAY - Open the connection immediately (normally, the connection
|
|
* is opened when the first message is logged).
|
|
* LOG_NOWAIT - Don't wait for child processes that may have been created
|
|
* while logging the message.
|
|
* LOG_ODELAY - The converse of LOG_NDELAY; opening of the connection is
|
|
* delayed until syslog() is called. (This is the default,
|
|
* and need not be specified.)
|
|
* LOG_PERROR - (Not in POSIX.1-2001 or POSIX.1-2008.) Print to stderr
|
|
* as well (Linux).
|
|
* LOG_PID - Include PID with each message.

/* The facility argument is used to specify what type of program is logging
|
|
* the message. This lets the configuration file specify that messages from

|
|
*
|
|
* LOG_AUTH - Security/authorization messages
|
|
* LOG_AUTHPRIV - Security/authorization messages (private)
|
|
* LOG_CRON - Clock daemon (cron and at)
|
|
* LOG_DAEMON - System daemons without separate facility value
|
|
* LOG_FTP - Ftp daemon
|
|
* LOG_KERN - Lernel messages (these can't be generated from user
|
|
* processes)
|
|
* LOG_LOCAL0 through LOG_LOCAL7 - Reserved for local use
|
|
* LOG_LPR - Line printer subsystem
|
|
* LOG_MAIL - Mail subsystem
|
|
* LOG_NEWS - USENET news subsystem
|
|
* LOG_SYSLOG - Messages generated internally by syslogd(8)
|

* LOG_UUCP - UUCP subsystem
