uint64_unpack - read an unsigned little-endian 64-bit integer
#include <uint64.h>
uint64 u;
void uint64_unpack(const char s[4],uint64 *u);
uint64 is a 64-bit unsigned integer type.
uint64_unpack portably reads a uint64 as stored on a little-endian architecture from s and writes it into u in the native byte order.
