** Syslog(Module)

Included Modules: Syslog::Constants

require 'syslog'

A Simple wrapper for the UNIX syslog system calls that might be handy
if you're writing a server in Ruby.  For the details of the syslog(8)
architecture and constants, see the syslog(3) manual page of your
platform.

Module Methods:

   open(ident = $0, logopt = Syslog::LOG_PID | Syslog::LOG_CONS,
		facility = Syslog::LOG_USER) [{ |syslog| ... }]

	Opens syslog with the given options and returns the module
	itself.  If a block is given, calls it with an argument of
	itself.  If syslog is already opened, raises RuntimeError.

	Example:
	  Syslog.open('ftpd', Syslog::LOG_PID | Syslog::LOG_NDELAY,
			      Syslog::LOG_FTP)

   open!(ident = $0, logopt = Syslog::LOG_PID | Syslog::LOG_CONS,
		facility = Syslog::LOG_USER)
   reopen(ident = $0, logopt = Syslog::LOG_PID | Syslog::LOG_CONS,
		facility = Syslog::LOG_USER)

	Same as open, but does a close first.

   opened?

	Returns true if syslog opened, otherwise false.

   ident
   options
   facility

	Returns the parameters given in the last open, respectively.
	Every call of Syslog::open resets these values.

   log(pri, message, ...)

	Writes message to syslog.

	Example:
	  Syslog.log(Syslog::LOG_CRIT, "the sky is falling in %d seconds!", 10)

   crit(message, ...)
   emerg(message, ...)
   alert(message, ...)
   err(message, ...)
   warning(message, ...)
   notice(message, ...)
   info(message, ...)
   debug(message, ...)

	These are shortcut methods of Syslog::log().  The lineup may
	vary depending on what priorities are defined on your system.

	Example:
	  Syslog.crit("the sky is falling in %d seconds!", 5)
 
   mask
   mask=(mask)

	Returns or sets the log priority mask.  The value of the mask
	is persistent and will not be reset by Syslog::open or
	Syslog::close.

	Example:
	  Syslog.mask = Syslog::LOG_UPTO(Syslog::LOG_ERR)

   close 

	Closes syslog.

   inspect

	Returns the "inspect" string of the Syslog module.

   instance

	Returns the module itself. (Just for backward compatibility)

   LOG_MASK(pri)

	Creates a mask for one priority.

   LOG_UPTO(pri)

	Creates a mask for all priorities up to pri.

** Syslog::Constants(Module)

require 'syslog'
include Syslog::Constants

This module includes the LOG_* constants available on the system.

Module Methods:

   LOG_MASK(pri)

	Creates a mask for one priority.

   LOG_UPTO(pri)

	Creates a mask for all priorities up to pri.
