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 only from within init/cleanup code, not from realtime tasks. This function is not available from user (non-realtime) code.
As in Linux.
