In kernel space, each rtapi_xxx or RTAPI_XXX identifier is mapped to the underlying kernel functionality, if available.
In userspace, or in kernels where the underlying functionality is not provided by a kernel, generally another implementation--possibly with reduced functionality--is provided. (For example, the userspace implementation for rtapi_device_register always succeeds)
Call from init/cleanup code and from realtime tasks. These functions will cause illegal instruction exceptions in userspace components, as well as in uspace rtapi_app when it is not setuid root.
As in Linux.
