# CoMarshalHresult

Marshals an HRESULT to the specified stream, from which it can be unmarshaled using the CoUnmarshalHresult function.

STDAPI CoMarshalHresult(

IStream * pStm, | //Pointer to the marshaling stream
HRESULT hresult | //HRESULT to be marshaled
); |

Parameters

pStm
  [in] Pointer to the marshaling stream.
hresult
  [in] HRESULT in the originating process.

Return Values

This function supports the standard return values E_OUTOFMEMORY and E_UNEXPECTED, as well as the following:

S_OK
  The HRESULT was marshaled successfully.
STG_E_INVALIDPOINTER
  Bad pointer passed in for pStm.
STG_E_MEDIUMFULL
  The medium is full.

Remarks

An HRESULT is process-specific, so an HRESULT that is valid in one process might not be valid in another. If you are writing your own implementation of IMarshal and need to marshal an HRESULT from one process to another, either as a parameter or a return code, you must call this function. In other circumstances, you will have no need to call this function.

This function perfoms the following tasks:

1. Writes an HRESULT to a stream.

2. Returns an IStream pointer to that stream.
