Call-stack for exceptions in C++

Question

Today, in my C++ multi-platform code, I have a try-catch around every function. In every catch block I add the current function\'s name to the exception and throw it again,

Answer 1

While quite a few counter-arguments have been made in the answers here, I want to note that since this question was asked, with C++11, methods have been added which allow you to get nice backtraces in a cross-platform way and without the need for a debugger or cumbersome logging:

Use std::nested_exception and std::throw_with_nested

It is described on StackOverflow here and here, how you can get a backtrace on your exceptions inside your code by simply writing a proper exception handler which will rethrow nested exceptions. It will, however, require that you insert try/catch statements at the functions you wish to trace.

Since you can do this with any derived exception class, you can add a lot of information to such a backtrace! You may also take a look at my MWE on GitHub or my "trace" library, where a backtrace would look something like this:

Library API: Exception caught in function 'api_function'
Backtrace:
~/Git/mwe-cpp-exception/src/detail/Library.cpp:17 : library_function failed
~/Git/mwe-cpp-exception/src/detail/Library.cpp:13 : could not open file "nonexistent.txt"
