You do this by supplying the UUID for the service class of the record. As the service class may be a single UUID or a list of UUIDs in the form of a DES, there are two overloaded functions. </p> <p>The steps to register a service are as follows: </p> <ol id="GUID-AFA9213B-869F-5DDB-9572-181F4B058626"><li id="GUID-CD2C1B73-F3C0-5A9E-AA50-7E29B7D9C84E"><p>Create a blank service record object, <xref href="GUID-9DDF886B-1556-30A2-A417-1919BA6D255A.dita"><apiname>TSdpServRecordHandle</apiname></xref>. </p> </li> <li id="GUID-60B2CB64-CAC7-5FF6-88B3-84D32A9C05F5"><p>If the service class attribute should be a single UUID, create and set a <xref href="GUID-FAD6BB78-84B7-335A-9D9C-3ADE7CF0958F.dita"><apiname>TUUID</apiname></xref> object.
