 // Description:

 // e32test\dll\t_oeexport_wins.cpp

 // Overview:

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

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

 // symbol export data.

 // API Information:

 // RProcess, RLibrary

 // Details:

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

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

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

 // dll without the named symbol data

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

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

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

 // an exe that doesn't contain a E32EmulExpSymInfoHdr

 // Platforms/Drives/Compatibility:

 // All

 // Assumptions/Requirement/Pre-requisites:

 // Failures and causes:

 // Base Port information:

 //
