This function unmarshals an HRESULT type from the specified stream.
Syntax
STDAPI CoUnmarshalHresult(
LPSTREAM pStm,
HRESULT* phresult
);
Parameters
- pStm
[in] Pointer to the stream from which the HRESULT is to be unmarshaled.
- phresult
[out] Pointer to the unmarshaled HRESULT.
Return Value
This function supports the standard return values E_OUTOFMEMORY and E_UNEXPECTED, as well as the following:
- S_OK
The HRESULT was unmarshaled successfully.
- STG_E_INVALIDPOINTER
pStm is an invalid pointer.
Remarks
Your application does not explicitly call this function unless performing custom marshaling with a special implementation of IMarshal, and your implementation needs to unmarshal an HRESULT.
The application must use CoUnmarshalHresult to unmarshal HRESULTs previously marshaled by a call to the CoMarshalHresult function.
This function performs the following tasks:
- Reads an HRESULT from a stream.
- Returns the HRESULT.
