31 | /* Hey look, some documentation [and in a place you expect to find it]! | |
32 | ||
33 | The main reference for the pei format is "Microsoft Portable Executable | |
34 | and Common Object File Format Specification 4.1". Get it if you need to | |
35 | do some serious hacking on this code. | |
36 | ||
37 | Another reference: | |
38 | "Peering Inside the PE: A Tour of the Win32 Portable Executable | |
39 | File Format", MSJ 1994, Volume 9. | |
40 | ||
41 | The *sole* difference between the pe format and the pei format is that the | |
42 | latter has an MSDOS 2.0 .exe header on the front that prints the message | |
43 | "This app must be run under Windows." (or some such). | |
44 | (FIXME: Whether that statement is *really* true or not is unknown. | |
45 | Are there more subtle differences between pe and pei formats? | |
46 | For now assume there aren't. If you find one, then for God sakes | |
47 | document it here!) | |
48 | ||
49 | The Microsoft docs use the word "image" instead of "executable" because | |
50 | the former can also refer to a DLL (shared library). Confusion can arise | |
51 | because the `i' in `pei' also refers to "image". The `pe' format can | |
52 | also create images (i.e. executables), it's just that to run on a win32 | |
53 | system you need to use the pei format. | |
54 | ||
55 | FIXME: Please add more docs here so the next poor fool that has to hack | |
56 | on this code has a chance of getting something accomplished without | |
ff0c9faf | 57 | wasting too much time. */ |
