    13 // Description:

    14 // e32test\dll\t_oeexport_wins.cpp

    15 // Overview:

    16 // Emulator version that tests it is possible to retrieve the 0th 

    17 // ordinal from exes and dlls that are marked as having named 

    18 // symbol export data.

    19 // API Information:

    20 // RProcess, RLibrary

    21 // Details:

    22 // - 	Test reading 0th ordinal from a dll which has a E32EmulExpSymInfoHdr 

    23 // struct at the 0th ordinal and verify the contents of the header

    24 // -	Test NULL is returned on attempts to get the 0th ordinal from a 

    25 // dll without the named symbol data

    26 // -	Test reading the named symbol data from an exe that contains a

    27 // E32EmulExpSymInfoHdr struct at the 0th ordinal and verify the contents

    28 // -	Test NULL is returned when attempting to read the 0th ordinal of

    29 // an exe that doesn't contain a E32EmulExpSymInfoHdr

    30 // Platforms/Drives/Compatibility:
