    1.18 +// Overview:
    1.19 +// Emulator version that tests it is possible to retrieve the 0th 
    1.20 +// ordinal from exes and dlls that are marked as having named 
    1.21 +// symbol export data.
    1.22 +// API Information:
    1.23 +// RProcess, RLibrary
    1.24 +// Details:
    1.25 +// - 	Test reading 0th ordinal from a dll which has a E32EmulExpSymInfoHdr 
    1.26 +// struct at the 0th ordinal and verify the contents of the header
    1.27 +// -	Test NULL is returned on attempts to get the 0th ordinal from a 
    1.28 +// dll without the named symbol data
    1.29 +// -	Test reading the named symbol data from an exe that contains a
    1.30 +// E32EmulExpSymInfoHdr struct at the 0th ordinal and verify the contents
    1.31 +// -	Test NULL is returned when attempting to read the 0th ordinal of
    1.32 +// an exe that doesn't contain a E32EmulExpSymInfoHdr
