Jimi,
I think what you would like to do is use the pfVertexAttr interface to
query the attribute data. When you call pfGeoArray::setMultiAttr, it
will return a pfVertexAttr*, which can be used to query the related
data. If you don't grab the return of the setMultiAttr function, then
the list of pfVertexAttr's can be searched through getNumAttrs() and
getNthAttr().
Hope this helps.
