29 | /* Hey look, some documentation [and in a place you expect to find it]! | |
30 | ||
31 | The main reference for the pei format is "Microsoft Portable Executable | |
32 | and Common Object File Format Specification 4.1". Get it if you need to | |
33 | do some serious hacking on this code. | |
34 | ||
35 | Another reference: | |
36 | "Peering Inside the PE: A Tour of the Win32 Portable Executable | |
37 | File Format", MSJ 1994, Volume 9. | |
38 | ||
39 | The *sole* difference between the pe format and the pei format is that the | |
40 | latter has an MSDOS 2.0 .exe header on the front that prints the message | |
41 | "This app must be run under Windows." (or some such). | |
42 | (FIXME: Whether that statement is *really* true or not is unknown. | |
43 | Are there more subtle differences between pe and pei formats? | |
44 | For now assume there aren't. If you find one, then for God sakes | |
45 | document it here!) | |
46 | ||
47 | The Microsoft docs use the word "image" instead of "executable" because | |
48 | the former can also refer to a DLL (shared library). Confusion can arise | |
49 | because the `i' in `pei' also refers to "image". The `pe' format can | |
50 | also create images (i.e. executables), it's just that to run on a win32 | |
51 | system you need to use the pei format. | |
52 | ||
53 | FIXME: Please add more docs here so the next poor fool that has to hack | |
54 | on this code has a chance of getting something accomplished without | |
ff0c9faf | 55 | wasting too much time. */ |
