DESCRIPTION

       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_pci_register  always
       succeeds)

REALTIME CONSIDERATIONS

       Typically, these functions may be called from realtime init/cleanup code.

RETURN VALUE

       As in Linux.
