SCLogInitOPIfaceCtx()

SCLogOPIfaceCtx* SCLogInitOPIfaceCtx	(	const char *	iface_name,
		const char *	log_format,
		int	log_level,
		const char *	arg
	)

Creates a new output interface based on the arguments sent. The kind of output interface to be created is decided by the iface_name arg. If iface_name is "file", the arg argument will hold the filename to be used for logging purposes. If iface_name is "syslog", the arg argument holds the facility code. If iface_name is "console", arg is NULL.

Parameters

iface_name	Interface name. Can be "console", "file" or "syslog"
log_format	Override for the global_log_format
log_level	Override for the global_log_level
log_level	Parameter required by a particular interface. Explained in the function description

Return values

iface_ctx

Pointer to the newly created output interface
