I searching to a easy way to write a value to a RTT::InputPort.
My use-case is that i want to have a initial value on a input port once
(like a default value).
This value is specified on the orogen-leven, and then passed to c++
generator.
The question is now, how can i easily write a value (once) to the under
laying port instance.
Do i really need to create a output_port, connect these ports, write to
the ouput_port, or is there a more easy way to fill the buffer with one
sample?
Greetings,
Matthias

Could you use setDataSample function, or does this not cover your use-case?

If you can depend on the rock toolchain, I would just make the Ruby
layer create an input writer and write the sample once.
