Parameter

[out] When successful, indirect pointer to the location of the 
IUnknown interface on the link source. In this case, the
implementation must call IUnknown::AddRef on the
parameter; it is the caller’s responsibility to call 
IUnknown::Release. If an error occurs, the
implementation sets ppunk to NULL.
