37  .SH DESCRIPTION
38  In kernel space, each rtapi_xxx or RTAPI_XXX identifier is mapped to the
39  underlying kernel functionality, if available.
40  
41  In userspace, or in kernels where the underlying functionality is not provided
42  by a kernel, generally another implementation--possibly with reduced
43  functionality--is provided.  (For example, the userspace implementation for
44  rtapi_device_register always succeeds)
45  .SH REALTIME CONSIDERATIONS
46  Typically, these functions may be called from realtime init/cleanup code.
47  .SH RETURN VALUE
48  As in Linux.
