Syslog routines

These are loosely based on the unix syslog(3) function and relatives.

type facility = [ `LOG_AUTH
       | `LOG_AUTHPRIV
       | `LOG_CONSOLE
       | `LOG_CRON
       | `LOG_DAEMON
       | `LOG_FTP
       | `LOG_KERN
       | `LOG_LOCAL0
       | `LOG_LOCAL1
       | `LOG_LOCAL2
       | `LOG_LOCAL3
       | `LOG_LOCAL4
       | `LOG_LOCAL5
       | `LOG_LOCAL6
       | `LOG_LOCAL7
       | `LOG_LPR
       | `LOG_MAIL
       | `LOG_NEWS
       | `LOG_NTP
       | `LOG_SECURITY
       | `LOG_SYSLOG
       | `LOG_USER
       | `LOG_UUCP ]

The assorted logging facilities. The default is `LOG_USER. You can set a new default with openlog, or give a specific facility per syslog call.

type flag = [ `LOG_CONS | `LOG_PERROR | `LOG_PID ]

Flags to pass to openlog. `LOG_CONS isn't implemented yet. LOG_NDELAY is mandatory and implied

type level = [ `LOG_ALERT
       | `LOG_CRIT
       | `LOG_DEBUG
       | `LOG_EMERG
       | `LOG_ERR
       | `LOG_INFO
       | `LOG_NOTICE
       | `LOG_WARNING ]

The priority of the error.

type t

the type of a syslog connection

val facility_of_string : string -> facility

given a string descibing a facility, return the facility. The strings consist of the name of the facility with the LOG_ chopped off. They are not case sensitive.

val openlog : ?logpath:string ->
       ?facility:facility -> ?flags:flag list -> string -> t

openlog ?(logpath=AUTODETECTED) ?(facility=`LOG_USER) ?(flags=[]) program_name, similar to openlog(3)

val syslog : ?fac:facility -> t -> level -> string -> unit

Same as syslog(3), except there's no formats.

val closelog : t -> unit

Close the log.
