Dynamic Linking

I've read the COFF file format and I'm trying to implement a program that reports all the COFF data, symbols etc. I can read the file header but my list of symbols is just s***.

Can some one please look at the code attached.

hmm ..
i'm unsure, but i can see things like

Code: Select all

struct coff_header *image;
...
symbol = (image + image->symbol_off + i);

you are of course aware that writing ptr+offset in C means (void*)ptr + offset * sizeof(<base type of ptr>), so ((dword*)p) + 1 == ((char*)p)+4

Thanks. Although I still don't completely understand the output. The name of the symbols are obviously right.

I've just found a page which seems to contain lots of useful info on the subject and on other stuff as well.

all of these things are also clearly described in the appendix of the Kernighan & Ritchie book about ANSI C ... that one is a must-read for all of you, young paddawan ...
