NAME
	CopyMem - general purpose memory copy function

   SYNOPSIS
	CopyMem( source, dest, size )
		 A0	 A1    D0

	void CopyMem(APTR,APTR,ULONG);

   FUNCTION
	CopyMem is a general purpose, fast memory copy function.  It can
	deal with arbitrary lengths, with its pointers on arbitrary
	alignments.  It attempts to optimize larger copies with more
	efficient copies, it uses byte copies for small moves, parts of
	larger copies, or the entire copy if the source and destination are
	misaligned with respect to each other.

	Arbitrary overlapping copies are not supported.

	The internal implementation of this function will change from
	system to system, and may be implemented via hardware DMA.

   INPUTS
	source - a pointer to the source data region
	dest  - a pointer to the destination data region
	size  - the size (in bytes) of the memory area.  Zero copies
		zero bytes
