Stack Trace Information

How can I find stack trace info without using any system function?
Ex
f1(){
..
f2();
}
f2(){
f3();
}
When we say f3.It should track f3->f2->f1.

In what language?
If f3() is a function, what is f3.It?

In C/C++.
f3() is also a function called in f2().

You could make a global stack and have every function push its name on when it is called, and have them take it off when they're done.
Or you could do something incredibly dirty like trying to read the function stack, by working down from the address of the parameters or something.

Do you mean to call the "show stack" function from within the call to f3, in which case I second towr's propositions, or do you mean to call f3 as an argument? In that case it is a matter of analyzing the source code and finding call references, which may not be unique.

You mean I need to push the function name in stack before calling the function?
In that way I need to modify the existing function.
Is there any way I can do it without modification of existing function?

But are you willing to modify f3?
You could run your program in a debugger, you can then set a breakpoint in f3, it will display the stack trace.
In java there is a library function that returns the stack trace. I guess such a library exists in C/C++. It could do so without calling the OS, since all necessary data is on the stack. So it wouldn't be a system call.
What is the context? What is it you are trying to do?

Sorry for late reply.

No. Existing function is not supposed to modify.
Yes there is function stacktrace() in c/c+. But All the compiler may not have this.

If you are worrying stacktrace() might not be available everywhere, that means you want it portable.
But your only chance to make it portable is to have the compiler or the runtime library get the information for you.
