/*
* Abstract:
* Turns on byte packing, which is necessary for passing information from
* system to system over a network to ensure no padding by the compiler has
* taken place.

/****h* Component Library/Structure Packing
* NAME
* Structure Packing
*
* DESCRIPTION
* The structure packing header files allow packing structures on byte
* boundaries.
*
* Structure packing should be used whenever a structure is transmitted
* between systems, as different platforms pad structures differently if
* they are not packed. Packing a structure that is not transmitted between
* systems can be detrimental to performance, as fields in the structure may
* not align properly for some platforms. Care must be taken when creating
* packed structures that the alignment rules for all platforms are followed.
*
* To pack a structure, include cl_packon.h before defining the structure, and
* include cl_packoff.h after the structure definition. Multiple structures
* can be packed between the two include statements if desired.
*
* The structure definition itself must use the PACK_SUFFIX keyword.
*
* EXAMPLE
* #include <complib/cl_packon.h>
*
* typedef _my_struct_t
* {
* uint64 large;
* uint32 medium;
* uint16 small;
*
* } PACK_SUFFIX my_struct_t;
* #include <complib/cl_packoff.h>
