44* NAME
45*	Structure Packing
46*
47* DESCRIPTION
48*	The structure packing header files allow packing structures on byte
49*	boundaries.
50*
51*	Structure packing should be used whenever a structure is transmitted
52*	between systems, as different platforms pad structures differently if
53*	they are not packed.  Packing a structure that is not transmitted between
54*	systems can be detrimental to performance, as fields in the structure may
55*	not align properly for some platforms. Care must be taken when creating
56*	packed structures that the alignment rules for all platforms are followed.
57*
58*	To pack a structure, include ipackon.h before defining the structure, and
59*	include ipackoff.h after the structure definition.  Multiple structures
60*	can be packed between the two include statements if desired.
61*
62*	The structure definition itself must use the PACK_SUFFIX keyword.
63*
64* EXAMPLE
65*	#include <complib/ipackon.h>
66*
67*	typedef _my_struct_t
68*	{
69*	    uint64 large;
70*	    uint32 medium;
71*	    uint16 small;
72*
73*	} PACK_SUFFIX my_struct_t;
74*	#include <complib/ipackoff.h>
