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 55 wasting too much time. */ 56 57 #ifndef GET_FCN_LNNOPTR 58 #define GET_FCN_LNNOPTR(abfd, ext) \ 59 H_GET_32
