Clean ways to do multiple undos in C

Yes, it’s quite common to use goto in such cases to avoid repeating yourself.

An example:

int hello() {
  int result;

  if (Do1()) { result = 1; goto err_one; }
  if (Do2()) { result = 2; goto err_two; }
  if (Do3()) { result = 3; goto err_three; }
  if (Do4()) { result = 4; goto err_four; }
  if (Do5()) { result = 5; goto err_five; }

  // Assuming you'd like to return 0 on success.
  return 0;

err_five:
  Undo4();
err_four:
  Undo3();
err_three:
  Undo2();
err_two:
  Undo1();
err_one:
  printf("Failed %i", result); 
  return result;
}

As always you probably also want to keep your functions small and batch together the operations in a meaningful manner to avoid a large “undo-code”.
