The standard says the parameters must all be int values. This is
an historic accident and would be done differently today. For
x86-64 all integer values are passed as 64-bit values and
therefore extending the API to copy 64-bit values instead of
32-bit ints makes sense. It does not break existing

that passing non-int values means undefined behavior. */
