regarding symbol table

[ranjith kumar]

Hi,

1) Given an executable file(say a.out) is it possible from which files
that executable is produced??

ie)If a.out is produced by
gcc 1.o 2.o -o a.out,
Given a.out file only ,can we determine a.out is produced from 1.o and 2.o??
If so how?

2) If we declare a newdatatype in a .c file , say

typedef struct mytype
{
int a;
int c;
}MYTYPE;

Given the executable file only, can we know any way that MYTYPE is a
datatye defined in the .c file???
I tried "nm a.out". It is not printing that kind of information.
Any help please.

Thanks.
