uint64_codes_when(?Uint64, ?Codes) is det[private]
Convert between a 64-bit unsigned integer value and its wirestream codes. This is a low-level predicate; normally, you should use template_message/2 and the appropriate template term.

SWI-Prolog allows integer values greater than 64 bits, so a range check is done.

This predicate delays until either Uint64 or Codes is sufficiently instantiated.

There is also a non-delayed uint64_codes/2
