{
    This file provides Endian Flipping routines for dealing with converting data
    between Big-Endian and Little-Endian machines.  These routines are useful
    when writing code to compile for both Big and Little Endian machines and  
    which must handle other endian number formats, such as reading or writing 
    to a file or network packet.
    
    These routines are named as follows:
    
        Endian<U><W>_<S>to<D>

    where
        <U> is whether the integer is signed ('S') or unsigned ('U')
        <W> is integer bit width: 16, 32, or 64 
        <S> is the source endian format: 'B' for big, 'L' for little, or 'N' for native
        <D> is the destination endian format: 'B' for big, 'L' for little, or 'N' for native
    
    For example, to convert a Big Endian 32-bit unsigned integer to the current native format use:
        
        long i = EndianU32_BtoN(data);
        
    This file is set up so that the function macro to nothing when the target runtime already
    is the desired format (e.g. on Big Endian machines, EndianU32_BtoN() macros away).
            
    If long long's are not supported, you cannot get 64-bit quantities as a single value.
    The macros are not defined in that case.

    For gcc, the macros build on top of the inline byte swapping
    routines from <libkern/OSByteOrder.h>, which may have better performance.
    
    
                                <<< W A R N I N G >>>
    
    It is very important not to put any autoincrements inside the macros.  This 
    will produce erroneous results because each time the address is accessed in the macro, 
    the increment occurs.

        CoreEndian flipping API.

        This API is used to generically massage data buffers, in
        place, from one endian architecture to another.  In effect,
        the API supports registering a set of callbacks that can
        effect this translation.  

        The data types have specific meanings within their domain,
        although some data types can be registered with the same
        callback in several domains.  There is no wildcard domain.

        A set of pre-defined flippers are implemented by the Carbon
        frameworks for most common resource manager and AppleEvent data
        types.
