Question

I want to trace each path of function calls.
For eg:

int a()
{
    b();
    return 1;
}
void b()
{
}
int main()
{
    int x=a();
    return 0;
}

So my call trace is main->a->b
In this manner I want to trace each set paths of calls.
I have thought of a depth first search. But i am not sure how this would go.
Can anyone suggest me any concrete method to be implemented in perl?
I will have C program file and will run a perl script over it to get call traces.

There are a number of free call-graph programs listed in this article, including egypt which is a small Perl script that uses gcc and Graphviz to generate the static call graph of a C program.
