For user applications to access the data received for a DataReader, they must use the type-specific derived class or set of functions in the C API. Thus for a user data type ‘Foo’, you must use methods of the FooDataReader class. The type-specific class or functions are automatically generated if you use RTI Code Generator. Else, you will have to create them yourself, see 17.2.8 Type Codes for Built-in Types for more details.
