Macros
#define	FML_BYTESWAP_16(n)   __builtin_bswap16(n)

Functions
template<typename T , class = std::enable_if_t<kIsByteSwappableV<T>>>
constexpr T	fml::ByteSwap (T n)
	Flips the endianness of the given value. The given value must be an integral type of size 1, 2, 4, or 8.
template<typename T , class = std::enable_if_t<kIsByteSwappableV<T>>>
constexpr T	fml::BigEndianToArch (T n)
	Convert a known big endian value to match the endianness of the current architecture. This is effectively a cross platform ntohl/ntohs (as network byte order is always Big Endian). The given value must be an integral type of size 1, 2, 4, or 8.
template<typename T , class = std::enable_if_t<kIsByteSwappableV<T>>>
constexpr T	fml::LittleEndianToArch (T n)
	Convert a known little endian value to match the endianness of the current architecture. The given value must be an integral type of size 1, 2, 4, or 8.

Variables
template<typename T >
constexpr bool	fml::kIsByteSwappableV = IsByteSwappable<T>::value
