Overview:

|
22 |
|
|
23 |
Emulator version that tests it is possible to retrieve the 0th
|
|
24 |
|
|
25 |
ordinal from exes and dlls that are marked as having named
|
|
26 |
|
|
27 |
symbol export data.

Details:

|
|

- Test reading 0th ordinal from a dll which has a E32EmulExpSymInfoHdr
|
|
40 |
|
|
41 |
struct at the 0th ordinal and verify the contents of the header
|
|
42 |
|
|
43 |
- Test NULL is returned on attempts to get the 0th ordinal from a
|
|
44 |
|
|
45 |
dll without the named symbol data
|
|
46 |
|
|
47 |
- Test reading the named symbol data from an exe that contains a
|
|
48 |
|
|
49 |
E32EmulExpSymInfoHdr struct at the 0th ordinal and verify the contents
|
|
50 |
|
|
51 |
- Test NULL is returned when attempting to read the 0th ordinal of
|
|
52 |
|
|
53 |
an exe that doesn't contain a E32EmulExpSymInfoHdr
