Syntax

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

Parameters

memid

Member identifier that indicates which marshaling information is needed.

pBstrMops

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.

Return Values

One of the values described in the following table is returned.

Value Description
S_OK Success.
E_OUTOFMEMORY Out of memory.
E_INVALIDARG One or more of the parameters 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.

Remarks

If the passed-in member identifier is MEMBERID_NIL, the function returns the opcode string for marshaling the members 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 identifier.
