Extended Connection Preferences API can be used by applications to set the SNAP ID prior to establishing a connection.


Specifying SNAP ID enables the applications to start a connection to a specific SNAP.


  1. Connect to socket server .

    RSocketServ ss;
  2. Open a RConnection object.

    RConnection conn;
    conn.Open( ss );
  3. Create a connection preference list and extended connection preferences object.

    TConnPrefList prefList;
    TExtendedConnPref preferences;    
  4. Set the SNAP ID using TExtendedConnPref::SetSnapId().

    preference.SetSnapId( 4 );
  5. Append the extended connection preferences to connection preference list.

    prefList.AppendL( &preferences );
  6. Start a connection with connection preferences.

    conn.Start( prefList );


The application is connected to the specified SNAP ID.
