This is generally the first interface class used by all client applications. It is used to make the primary connection to the location server. After the primary connection has been established, its handle is passed as a parameter of the Open methods of RPositioner to create a "sub-session".

The RPositionServer class can also be used to discover what position technology "modules" are available. However, this is only required if a client application actually needs to use a particular module. It is also used for requests to clear(empty) the last known position store.

Asynchronous requests can be cancelled using the method CancelRequest() with a value from the enumeration _TReqestId corresponding to the particular operation being cancelled.
