Question

Anyone know what library/header is required to use the make64 high32 and low32 functions on
MacOS or linux. Couldn’t find anything on the web.

 uint64_t make64(uint32_t high, uint32_t low);
 uint32_t high32(uint64_t value);
 uint32_t low32(uint64_t value);

Thanks

I don’t know any library with these functions, just write them:

uint64_t make64(uint32_t high, uint32_t low)
{
    return (uint64_t) high << 32 | low;
}

uint32_t high32(uint64_t value)
{
   return value >> 32;
}

uint32_t low32(uint64_t value)
{
    return value;
}
