| 26 | /* Hey look, some documentation [and in a place you expect to find it]! |
| 27 | |
| 28 | The main reference for the pei format is "Microsoft Portable Executable |
| 29 | and Common Object File Format Specification 4.1". Get it if you need to |
| 30 | do some serious hacking on this code. |
| 31 | |
| 32 | Another reference: |
| 33 | "Peering Inside the PE: A Tour of the Win32 Portable Executable |
| 34 | File Format", MSJ 1994, Volume 9. |
| 35 | |
| 36 | The *sole* difference between the pe format and the pei format is that the |
| 37 | latter has an MSDOS 2.0 .exe header on the front that prints the message |
| 38 | "This app must be run under Windows." (or some such). |
| 39 | (FIXME: Whether that statement is *really* true or not is unknown. |
| 40 | Are there more subtle differences between pe and pei formats? |
| 41 | For now assume there aren't. If you find one, then for God sakes |
| 42 | document it here!) |
| 43 | |
| 44 | The Microsoft docs use the word "image" instead of "executable" because |
| 45 | the former can also refer to a DLL (shared library). Confusion can arise |
| 46 | because the `i' in `pei' also refers to "image". The `pe' format can |
| 47 | also create images (i.e. executables), it's just that to run on a win32 |
| 48 | system you need to use the pei format. |
| 49 | |
| 50 | FIXME: Please add more docs here so the next poor fool that has to hack |
| 51 | on this code has a chance of getting something accomplished without |
| 52 | wasting too much time. |
