OK, well apparently on OS X, either RME didn't use standard macros for
this (most likely), or there are no standard macros for this.

Hi Paul,
i converted b_swap's to cpu_to_xxx and xxx_to_cpu macros, and during
that, found that the following part may not work correctly on BE.
static inline unsigned long long hdsp_read64 (hdsp_t *hdsp, int reg)
{
unsigned long long val;
val = hdsp_read(hdsp, reg);
val =
