Detailed Description

Author: Endace Technology Limited - Jason Ish jason.nosp@m..ish.nosp@m.@enda.nosp@m.ce.c.nosp@m.om

This file provides a basic configuration system for the IDPS engine.

NOTE: Setting values should only be done from one thread during engine initialization. Multiple threads should be able access read configuration data. Allowing run time changes to the configuration will require some locks.

Todo:: Consider having the in-memory configuration database a direct reflection of the configuration file and moving command line parameters to a primary lookup table?

Todo:: Get rid of allow override and go with a simpler first set, stays approach?

int ConfGet	(	const char *	name,

	)

Retrieve the value of a configuration node.

This function will return the value for a configuration node based on the full name of the node. It is possible that the value returned could be NULL, this could happen if the requested node does exist but is not a node that contains a value, but contains children ConfNodes instead.

Parameters

name	Name of configuration parameter to get.
vptr	Pointer that will be set to the configuration value parameter. Note that this is just a reference to the actual value, not a copy.

Return values

1	will be returned if the name is found, otherwise 0 will be returned.
