/*
**  SYSLOG.H -- declarations for system logging program
**
**	These are used as the first parameter to logmsg().
**	Their meanings are approximately as follows:
**
**	LOG_ALERT -- this priority should essentially never
**		be used.  It applies only to messages that
**		are so important that every user should be
**		aware of them, e.g., a serious hardware failure.
**	LOG_SALERT -- messages of this priority should be
**		issued only when immediate attention is needed
**		by a qualified system person, e.g., when some
**		valuable system resource dissappears.  They get
**		sent to a list of system people.
**	LOG_EMERG -- Emergency messages are not sent to users,
**		but represent major conditions.  An example
**		might be hard disk failures.  These could be
**		logged in a separate file so that critical
**		conditions could be easily scanned.
**	LOG_ERR -- these represent error conditions, such as soft
**		disk failures, etc.
**	LOG_CRIT -- such messages contain critical information,
**		but which can not be classed as errors, for example,
**		'su' attempts.
**	LOG_WARNING -- issued when an abnormal condition has been
**		detected, but recovery can take place.
**	LOG_NOTICE -- something that falls in the class of
**		"important information"; this class is informational
**		but important enough that you don't want to throw
**		it away casually.
**	LOG_INFO -- information level messages.  These messages
**		could be thrown away without problems, but should
**		be included if you want to keep a close watch on
**		your system.
**	LOG_DEBUG -- it may be useful to log certain debugging
**		information.  Normally this will be thrown away.
**	
**	It is expected that the kernel will not log anything below
**	LOG_ERR priority.
