Data Structures

Here are the data structures with brief descriptions:

_U_byte	Accesses an 8 bit quantity as both a signed and unsigned byte
_U_int	Accesses a 32 bit quantity as narrower integer types (shorts and chars)
_U_int_as_shorts	Internal structure which sets the ordering for assessing the shorts within an int
_U_longlong	Accesses a 64 bit quantity as narrower integer types (ints, shorts and chars)
_U_longlong_as_ints	Internal structure which sets the ordering for assessing the ints within a long long int
_U_short	Accesses a 16 bit quantity as narrower integer types (chars)
_U_short_as_bytes	Internal structure which sets the ordering for assessing the bytes within a short
A_int	Union an unsigned int against 2 unsigned shorts and 4 unsigned chars
A_longlong	Union an unsigned long long against 2 unsigned ints, 4 unsigned shorts and 8 unsigned chars
A_short	Union an unsigned short against 2 unsigned chars
