No, you read the VxWorks documentation correctly. However, what the VxWorks documentation fails to mention (not that it could if it wanted to) is that NI has not implemented the use of RTP's in the variant of VxWorks that we're using for our cRIO product line. So, all calls you make are kernel calls since there is no concept of "user mode" in what you're using.
Of course, this is something that is subject to change in future versions of the VxWorks port for cRIO, but it's most likely not going to happen in even the next major release.
