System.Posix.Syslog.Options

Description

FFI bindings to syslog(3) from POSIX.1-2008. This module is intended for purposes of low-level implementation. Users of this library should prefer safer and more convenient API provided by System.Posix.Syslog.

Synopsis

Documentation

data Option Source #

The function openlog allows one to configure a handful of process-wide options that modify the behavior of the syslog function. These options are pid, cons, odelay, and ndelay.

Constructors

LogPID

Log the pid with each message.

Console

Log on the console if errors occur while sending messages.

DelayedOpen

Delay all initialization until first syslog() call (default).

ImmediateOpen

Initialize the syslog system immediately.

DontWaitForChildren

The syslog system should not attempt to wait for child process it may have created. This option is required by applications who enable SIGCHLD themselves.
