User Data Type Support

Files generated by rtiddsgen that implement the type specific APIs required by the DDS specification, as described in the User Data Type Support, where:

• FooTypeSupport = HelloWorldTypeSupport
• FooDataWriter = HelloWorldDataWriter
• FooDataReader = HelloWorldDataReader

The following files are always generated in the C++/CLI language, even when code is generated with the -language C# option, because they depend on unmanaged code that ships with RTI Connext. Once compiled, the code can be used from either C++/CLI or C# code; see the C# publisher and subscriber example code.
