/**
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
