+// 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:
