Re: I Have A Question About Pointers

I'm not on the RT team, but the reason I was given was that when they did the board support, the RTP introduced too much overhead for the I/O drivers. Until FRC, the only C programmers for the cRIO were the NI developers, so they kept it in kernel mode. At that time, all other users of the cRIO used LV.

Exposing the C/C++ interfaces and tools, going to RTP was evaluated, but there would be a lot of work and testing involved, and it would mess with the I/O rates of various drivers.
