    331) the doc for "DosQueryPathInfo" says that each GEA2 element must be DWORD aligned.I don't know if that is really true. I don't think so.[[BR]]
    4 2) the GEA2List is TIGHTLY PACKED. That means you cannot allocate a separate buffer for the list and the GEA2. Likewise the GEA2LIST structure does not give you room for a complete GEA2 structure. That's because the EA Name has to DIRECTLY follow the GEA2 structure and it is of variable length:
     42) the FEA2List and GEA2List are TIGHTLY PACKED. That means you cannot allocate a separate buffer for the list and the FEA2 / GEA2. Likewise the FEA2LIST / GEA2LIST structure does not give you room for a complete FEA2/GEA2 structure. That's because the EA Name has to DIRECTLY follow the FEA2/GEA2 structure and it is of variable length, FEA2, the value of the EA follows the EA Name:
