How to find the return adress of the calling code of a procedure/function?
Where in the stack is the information to the return adress?
stack + - x?
asm
mov eax , [ ebp + 4 ]
end;
eax is the return adress
This will only work on i386 and might even work only with certain
calling conventions (don't know exactly whether other calling
conventions on i386 don't use EAX for the result value).
How to acess to the information in assembler?
Is it in every processor architecture possible, for example ARM?
(actually 80x86).
Is it different in 32 / 64 bit?
Why don't you try this:
