Functions
DDR_ErrorCode	ddr_openmemoryblock (blockName, Handle dataHandle)
	Open access to a memory block for exclusive use, given the name of the memory block.

DDR_ErrorCode	ddr_closememoryblock (Handle dataHandle)
	Close access to a memory block previously opened by ddr_openmemoryblock(), thus releasing it for others to open.

DDR_ErrorCode	ddr_getmemorysize (Handle dataHandle, ValueHandle memorySizeInChunks)
	Retrieve the number of chunks in the memory block indicated by the handle to the successfully opened memory block.

DDR_ErrorCode	ddr_getdatachunk (Handle dataHandle, int chunkOffset, ValueHandle value)
	Read a single 32-bit value at the given offset in the memory block indicated by the specified handle.

DDR_ErrorCode	ddr_setdatachunk (Handle dataHandle, int chunkOffset, int value)
	Writes a single 32-bit value to the given offset in the memory block indicated by the specified handle.

Variables
int	DDR_MAX_OFFSET = 32
	All offsets must from 0 to 1 less than this value.

str	BLOCK_NAME_0 = "gorp"
	Name of the first block.

str	BLOCK_NAME_1 = "baba"
	Name of the second block.

str	BLOCK_NAME_2 = "yaga"
	Name of the third block.

os	dll_path = os.path.join(os.path.dirname(__file__), "Adapter_BackEnd")
	Path to the Adapter_BackEnd DLL that will be loaded by ctypes.

	else :

cdll	adapter_backend = cdll.LoadLibrary(dll_path)
	Instance of a CDLL object representing the loaded Adapter_BackEnd DLL.
