This method retrieves marshaling information.

HRESULT GetMops( 
  MEMBERID memid, 
  BSTR FAR* pBstrMops 
);

Parameters

  • memid
    [in] Member identifier that indicates which marshaling information is needed.
  • pBstrMops
    [out] On return, pointer to the opcode string used in marshaling the members of the structure described by the referenced type description, or returns NULL if there is no information to return.
