In ixmldomdocumentLoadWhether the method return value has a bug

Ixmldomdocument Load When an XML file is returned, the returned value is inconsistent with the one described on msdn.
Msdn says:
Return values

The value returned if successful.


The value returned ifLoadFails.


The value returned if the issuccessful parameter is null.

I used this:

Coinitialize (null );
 IxmldomdocumentptrPdoc = NULL;
Hresult hR = pdoc. createinstance (_ uuidof (domdocument30 ));
If (! Succeeded (HR ))
Trace ("error: cannot create domdocument! \ N ");
HR = pdoc->Load(". \ Test. xml ");

Debugging successfulLoadThe HR value is-1.
LoadThe HR value is 0 in case of failure.
This is different from what msdn says.
