Yesterday my exams session finally ended, I’m really satisfied about the results achieved, but during the studying period I was eager to get back to coding…

Today I fixed bug #0000008, a fastidious one which caused program termination if the user tried to take a screenshot after having deleted the hidden directory inside his home where settings and images are saved by default. 🙂

The first thing I thought was that I was missing a fopen() return code check, but, fortunately for my reputation, it wasn’t the case. 😉

// Opening output file
if((fp = fopen(filename, "wb")) == NULL)
{
  throw Exception("Screen", "fopen error");
  return -1;
}

The problem, as the shell output was suggesting, was related to the exception system: the fopen() exception was never caught.

Just changing this:

case SDLK_F4:
  screen->TakeScreenshot();
  break;

into this:

case SDLK_F4:
  try
  {
    screen->TakeScreenshot();
  }
  catch(Exception e)
  {
    e.PrintError();
  }
  break;

fixed everything.

Have a look at r622 log and at mars.cpp changes and remember to catch all the exception you may throw. 😉
