- 2You've provided no information here that can be used to help, and asked nothing specific. Without knowing what OS and compiler you're using, there's no information. As you've phrased it, an answer of "Yes, there's a way to do it in C" or "No, there's no way to do it in C" would be acceptable answers, which obviously would not be useful. If you want help here, you need to be much more specific about what you're asking, and provide more information about what environment you're using. The FAQ has some tips on how to ask better questions.Ken White– Ken White2013-03-01 03:36:47 +00:00Commented Mar 1, 2013 at 3:36

If the platform is linux (and I believe in OSX too), you could use backtrace and backtrace_symbols to achieve what you want.
As per the notes section of backtrace
The symbol names may be unavailable without the use of special linker options. For systems using the GNU linker, it is necessary to use the -rdynamic linker option. Note that names of "static" functions are not exposed, and won't be available in the backtrace.
