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