ITypeInfo::GetMops

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

Retrieves marshaling information.

Parameters

memid: The member ID that indicates which marshaling information is needed.
pBstrMops: On return, contains a pointer to the opcode string used in marshaling the fields of the structure described by the referenced type description, or returns Null if there is no information to return.

Return Value

The return value obtained from the returned HRESULT is one of the following:

Return value	Meaning
S_OK	Success.
E_OUTOFMEMORY	Out of memory.
E_INVALIDARG	One or more of the arguments is invalid.
TYPE_E_IOERROR	The function could not read from the file.
TYPE_E_UNSUPFORMAT	The type library has an older format.
TYPE_E_INVALIDSTATE	The type library could not be opened.
TYPE_E_ELEMENTNOTFOUND	The element was not found.
TYPE_E_WRONGTYPEKIND	Type mismatch.

Comments

If the passed-in member ID is MEMBERID_NIL, the function returns the opcode string for marshaling the fields of the structure described by the type description. Otherwise, it returns the opcode string for marshaling the function specified by the index.

If the type description inherits from another type description, this function recurses on the base type description, if necessary, to find the item with the requested member ID.
