phresult
);

Parameters

pStm

[in] Pointer to the stream from which the HRESULTis to be unmarshaled.

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 CoUnmarshalHresultto unmarshal HRESULTs previously marshaled by a call to the CoMarshalHresultfunction.

This function performs the following tasks:

  1. Reads an HRESULT from a stream.

  2. Returns the HRESULT.
