  DESCRIPTION OF CHANGE........................

  09/17/2003 Greg Basler                       CIGI_CR_DR_1
  Initial Release.

  01/21/2005 Greg Basler                       Version 1.5
  Defined _EXPORT_CCL_ for exporting the class in a Windows DLL.

  01/21/2005 Greg Basler                       Version 1.5
  Removed the inline defnitions for the PackedPointer union and included the 
  CigiTypes.h header.

  01/21/2005 Greg Basler                       Version 1.5
  Added modifiers to export the CigiSwap2, CigiSwap4, and CigiSwap8 functions 
  when built as a Windows DLL.

  01/21/2005 Greg Basler                       Version 1.5
  Changed native C++ types to use CCL-defined types instead where appropriate.

  06/23/2006 Greg Basler                       Version 1.7.1
  Changed native char and unsigned char types to CIGI types Cigi_int8 and 
  Cigi_uint8.

  11/20/2007 Greg Basler                       Version 2.0.0
  Changed CigiCopy8 to make sure that it works for big endian and non-intel
  machines.

double word pointed to by dest.

Parameters:

	_dest_	- Specifies where the double word should be placed
	_src_	- Specifies the source double word to copy.

CIGI_SPEC void CigiSwap2	(	void *	dest,
		const void *	src
	)

Byte swaps the Cigi_int16 pointed to by src and places the result into the Cigi_int16 pointed to by dest.

Parameters:

	dest	- Specifies where the byte swapped Cigi_int16 should be placed
	src	- Specifies the source Cigi_int16 to byte swap.
