Interface to be implemented by objects used to provide system dependent data
for a transfer operation. Those objects usually also implement XTransferable.
Called by a data consumer to obtain a system specific data object from the
source.
The data object is returned in an any. The contained type may differ on
different platforms.

Parameter aProcessId
The argument aProcessId is a process identifier of the caller's process.
The interface implementation must ensure that the system data object can be
used in that process. If the data object is not valid in the caller process
then the returned any must be empty.
Returns
The system dependent data object.
Notes:Under Windows the returned any contains an unsigned long which represents a pointer to
an IDataObject interface. The caller of getData has to release the data
object (IDataObject::Release) if it is no longer needed.
The caller must also make sure that the current thread has been initialized for
OLE (use OleInitialize).
