	@header SCDynamicStore
	@discussion The SCDynamicStore API provides access to the key-value
		pairs in the dynamic store of a running system.  The dynamic
		store contains, among other items, a copy of the configuration
		settings for the currently active set (which is sometimes
		refered to as the location) and information about the current
		network state.

		The functions in the SCDynamicStore API allow you to find
		key-value pairs, add or remove key-value pairs, add or change
		values, and request notifications.

		To use the functions of the SCDynamicStore API, you must first
		establish a dynamic store session using the SCDynamicStoreCreate
		function.  When you are finished with the session, use CFRelease
		to close it.
