SDL 2| Error 3221225477

tristan1333 (49)
Hello, I'm trying to learn SDL 2.0. I understand that the error has to do with trying to access memory that has not been allocated, but I am absolutely uncertain on how to go about fixing this. Could anyone give some clues or answers if possible on how to fix the issue?

Hi Tristan

I'm not at home right now and I do not see an obvious error, would you mind using the code tags?

You should be careful with using the VSYNC, I've had various issues with that flag.

I'm not sure if passing a null pointer to SDL_DestroyWindow is allowed or not (the wiki doesn't say). Remove the first call to SDL_DestroyWindow in your code anyhow. It is not necessary to destroy any windows at that location because there are no windows to destroy.

Alright, I added in the code tags. @Peter87, I see what you mean, I removed that, still getting the error however.
