How to make a destructor without OOP?

Question

C++ / C#

There is a console application in C ++, purely "functional style"
Sometimes it kicks it out with an error, it just kicks it out and that's it.
And how to make it so that before this knocking out the program has time to do a couple of actions - for example, send a request to the database?

Answer 1

You can convert system and hardware exceptions to C++ (windows) exceptions.
_set_se_translator + project /EHa

Answer 2

int main(int argc, char* argv[])
{
  try {
    //все что было в main
  } catch (exc) {
    // отправить запрос на базу;
    // выйти с ошибкой;
    return 1;
  }
  return 0;
}
