 // Description:

 // e32test\dll\t_oeexport.cpp

 // Overview:

 // Tests it is possible to retrieve the 0th ordinal from exes and dlls

 // that are marked as having named symbol export data.  This is loaded

 // as non-XIP so loader fixups of 0th ordinal imports can be tested

 // API Information:

 // RProcess, RLibrary

 // Details:

 // - 	Test reading 0th ordinal from a dll which has a E32EpocExpSymInfoHdr 

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

 // -	Test attempts to get the 0th ordinal from a dll without the named symbol 

 // data returns NULL

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

 // E32EpocExpSymInfoHdr struct at the 0th ordinal and verify the contents

 // -	Test import fixups has correctly fixed up the 0th ordinal of the static

 // dependencies to this stdexe

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

 // an exe that doesn't contain a E32EpocExpSymInfoHdr

 // Platforms/Drives/Compatibility:

 // All

 // Assumptions/Requirement/Pre-requisites:

 // Failures and causes:
