);

Parameters

[in] pstm

A pointer to the stream from which the HRESULT is to be unmarshaled.

S_OK
 The HRESULT was unmarshaled successfully.

Remarks

You do not explicitly call this function unless you are performing custom marshaling (that is, writing your own implementation of IMarshal), and your implementation needs to unmarshal an HRESULT.

You must use CoUnmarshalHresult to unmarshal HRESULT values previously marshaled by a call to the CoMarshalHresult function.

This function performs the following tasks:

  1. an HRESULT from a stream.
  2. Returns the HRESULT.
