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_byteorder_register always succeeds) .SH REALTIME CONSIDERATIONS May be used at any time. .SH RETURN VALUE As in Linux. .SH SEE ALSO
