sl@0: // e32test\dll\t_oeexport_wins.cpp
sl@0: // Overview:
sl@0: // Emulator version that tests it is possible to retrieve the 0th 
sl@0: // ordinal from exes and dlls that are marked as having named 
sl@0: // symbol export data.
sl@0: // API Information:
sl@0: // RProcess, RLibrary
sl@0: // Details:
sl@0: // - 	Test reading 0th ordinal from a dll which has a E32EmulExpSymInfoHdr 
sl@0: // struct at the 0th ordinal and verify the contents of the header
sl@0: // -	Test NULL is returned on attempts to get the 0th ordinal from a 
sl@0: // dll without the named symbol data
sl@0: // -	Test reading the named symbol data from an exe that contains a
sl@0: // E32EmulExpSymInfoHdr struct at the 0th ordinal and verify the contents
sl@0: // -	Test NULL is returned when attempting to read the 0th ordinal of
sl@0: // an exe that doesn't contain a E32EmulExpSymInfoHdr
sl@0: // Platforms/Drives/Compatibility:
sl@0: // All
