Class RSdp

class RSdp : public RSessionBase;

Description

Provides a session to the Service Discovery Database.

Used to create subsessions to database functionality. A clients must create and connect a session, before using a RSdpDatabase subsession to access the database.

Derivation

• RHandleBase - A handle to an object.

• RSessionBase - Client-side handle to a session with a server.

• RSdp - Provides a session to the Service Discovery Database.
