Code execution Tracing

[Sabiyur]

Hi All,
I don't know whether this is the right forum to post this
question.
If not, Please forgive me.

I want to write my own tool which can trace the code execution (print
the sequence of function execution into a file).
But I cannot change the source code. (i.e.) I cannot write some Trace
macros
into source code.

I don't have idea on how to do that?
How does some process can trance the execution of other process?
I know some tools like Rational -Purecoverage is doing that.
How it does?
Any help welcome.

Thanks
Sabiyur

Sounds like you want to write your own debugger, but only write the
functions into a file. This is compiler specific but when you compile in
debug code there are "hooks" that are generated that the debugger can catch
and flow accordingly.

You'll need to look at your specific compiler I believe. If you are using
an open source compiler it should be a lot easier.
