Insert std::cout in the beginning of a function or all functions using a eclipse plugin

I often need to find out which functions are getting called in a C++ file. I am using Eclipse 3.7.0. The C++ file may be huge. I want to write a plugin which will detect the beginning of a function and insert a std::cout << "Function Name called !!" << std::endl

at the beginning in the code editor window. I think eclipse already detects functions since it does display the entire file structure in the Outline view. I would like to use this information to inject the cout statements. The 'Function Name' part should be replaced by the actual function name in the definition part of the function.

Is this even possible ? Where would I start ?

It would be even more awesome if I could insert couts automatically into all functions which call a particular function(say the one the cursor is in).

See this: http://stackoverflow.com/questions/5816950/automatic-tracing-of-program-execution, the GCC option `-finstrument-functions` will interest you. – Matthieu Rouget Jun 13 '13 at 09:27
Is there an option for ICC as well ? – safe_malloc Jun 13 '13 at 09:29

Looks like to be a `-f[no-]instrument-functions` option in ICC, it should be that. – Matthieu Rouget Jun 13 '13 at 09:31
Thanks Matthieu ! This option is certainly very useful. I would like to also try an option that lets me select a single c++ file or function, so not all functions get instrumented. – safe_malloc Jun 13 '13 at 09:33
