This is an erlang port driver for interacting with syslog.

./rebar3 compile

You should have a look at syslog.h.

In another shell :

$ tail -f /var/log/syslog

Or, for mac users :

$ tail -f /var/log/system.log

In erlang shell :

$ erl> syslog:start().> {ok,Log} = syslog:open("Beuha", [cons, perror, pid], local0).> syslog:log(Log, err, "Damned").> syslog:log(Log, info, "process count: ~w", [length(processes())]).

Ident is an arbitrary string
Logopt is an atom or array of atom, you can use a number if you're brave enough :

• pid
• cons
• odelay
• ndelay
• perror

Facility is an atom :

• kern
• user
• mail
• daemon
• auth
• syslog
• lpr
• news
• uucp
• cron
• authpriv
• ftp
• netinfo
• remoteauth
• install
• ras
• local0
• local1
• local2
• local3
• local4
• local5
• local6
• local7

Theopen call returns either{ok, Log} whereLog is a syslog handlethat can be passed to subsequentlog andclose calls, or it will throw{error, badarg}.

Log is a syslog handle returned fromopen
Priority can be a number or better, an atom :

• emerg
• alert
• crit
• err
• warning
• notice
• info
• debug

Message is a string.

Same as above, but allows for the construction of log messages similar toformatting strings viaio_lib:format/2, whereFormatMsg indicates theformatting instructions andFormatArgs is a list of arguments to beformatted.
