How to get the function name while in a function for debug strings?

Question

I want to output the function name each time it is called, I can easily copy and paste the function name, however I wondered if there was a shortcut that would do the job for me

Answer 1

If you check out boost there is a macro BOOST_CURRENT_FUNCTION that is portable across platforms. In the C99 standard there is a compiler variable __func__ that has the desired effect. I believe has been accepted into the C++0x standard. A reasonable number of compilers will already support this.
