title: what is the @number in the dumpbin exports output
body: <p>Using <code>DUMPBIN</code> on a C++ .DLL (or IMPLIB .LIB file) with /EXPORTS or /IMPORTS I see syntax in the output like the following:</p>
  
  <pre><code>Exports
  
  ordinal    name
  
        _CloseConduit@4
        _ConduitPort
        _GetConduitVersion@4
        _GetStatusConduit@8
        _GetTimeout@0
        _OpenConduit@4
  </code></pre>
  
  <p>I could not find anywhere a definition of what the <code>@n</code> designation means.  I finally have concluded that it's the number of bytes of argument data, but it leaves me a little nervous depending on inference from a few examples.  Can anyone point to a reference, or say with any authority, what the number here means?</p>
