/* 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. */ |
