    15 // Overview:
       
    16 // Tests it is possible to retrieve the 0th ordinal from exes and dlls
       
    17 // that are marked as having named symbol export data.  This is loaded
       
    18 // as non-XIP so loader fixups of 0th ordinal imports can be tested
       
    19 // API Information:
       
    20 // RProcess, RLibrary
       
    21 // Details:
       
    22 // - 	Test reading 0th ordinal from a dll which has a E32EpocExpSymInfoHdr 
       
    23 // struct at the 0th ordinal and verify the contents of the header
       
    24 // -	Test attempts to get the 0th ordinal from a dll without the named symbol 
       
    25 // data returns NULL
       
    26 // -	Test reading the named symbol data from an exe that contains a
       
    27 // E32EpocExpSymInfoHdr struct at the 0th ordinal and verify the contents
       
    28 // -	Test import fixups has correctly fixed up the 0th ordinal of the static
       
    29 // dependencies to this stdexe
       
    30 // -	Test NULL is returned when attempting to read the 0th ordinal of
       
    31 // an exe that doesn't contain a E32EpocExpSymInfoHdr
