Constructor & Destructor Documentation

◆ SyslogSink()

Sawyer::Message::SyslogSink::SyslogSink	(	const char *	ident,
		int	option,
		int	facility
	)

protected

Constructor for derived classes.

Non-subclass users should use instance instead.

Member Function Documentation

◆ instance()

static SyslogSinkPtr Sawyer::Message::SyslogSink::instance	(	const char *	ident,
		int	option,
		int	facility
	)

inlinestatic

Allocating constructor.

Constructs a new message sink that sends messages to the syslog daemon. The syslog API doesn't use a handle to refer to the syslog, nor does it specify what happens when openlog is called more than once, or whether the ident string is copied. Best practice is to use only constant strings as the ident argument.
