Resolution:
There is currently no support of RVFT in the SDK API. Product development is looking into how to best include RVFT in SDK and may provide support in a future release. A user who wishes to implement RVFT can use the RV API directly and access sessions/transports through MRvSession Class.

Please heed to the caution on using RVFT APIs directly in "Genral SDK
Best Practices" in SDK 5.0.x document:

"It is not advisable to use direct calls to the TIBCO Rendezvous API within
a custom adapter.
Using direct calls makes the custom adapter less portable and more difficult
to upgrade to newer versions of the SDK. However, in some cases using a
direct call to a TIBCO Rendezvous API is the only workaround available. For
example, an adapter design may rely on a TIBCO Rendezvous feature not
available in the SDK API, such as RV message queue control or RVFT protocol."

Please see the attached C++ and Java examples.
