Dear all,

I need to run a program, and When it perform an action, i see its
source, because i had find out which function do the given action.
So i need to tell to gdb that it generate automatically source that i
can see immedialy source of that function.

Yours,
Mohsen

Dear all,

I have a binary file what i compile it with -g.So i need to perform a
set of action in my computer and see behavior of my file, This mean , i
need to see functions of run when i perform those set of actions, So i
need to tell to gdb : Please print source of which peace of program that
running.
How i do it?

Yours,
Mohsen

You are using C ??
I don’t think you can assume you have read access to a file that you
are trying to executing,
apart from that why cant you just use GDB to do that whenever it is required.

Are you talking about Printing source lines
(http://sunsite.ualberta.ca/Documentation/Gnu/gdb-4.18/html_chapter/gdb_8.html
) ??

You suppose my program has 10 functions, and my program in running now
by gdb, i wanna know when i send signal x y z to my program, myprgram
call which function, So i need to a command same as list but immediately
print source of peace of running.

Maybe "handle" is what you want?

You can arrange to stop on each signal x, y, and z, then step into the 
handlers for each as they arrive.

As i understood it, he wants to be able to see whats happening as the program executes normally, much like a strace or truss, but printing the according source information. is this correct?

Yes, Of course,For instance, if your program run function myfunc()
agains signal OOO, i can see source of myfunc and name of myfunc(), of
course, name of function is very important.

Dear Andrew Please attention to previous email...My mean is not

Your question make absolutely no sense (to me).

Can you try to ask it in a more concrete, or a different fashion?
