Hi,
how can I know if my surface is just free or not?
tnx
I’m pretty sure you can just do this:
if (TheSurface==NULL)
{
//do whatever you would do if that’s the case
}
What do you mean by “free”…?
If you still have a pointer to a surfaces after it’s been passed to
SDL_FreeSurface(), you have an invalid pointer. There is generally no
reliable way of checking for that.
You should make it a habit to “destroy” all pointers to an object
after freeing it, so you don’t accidentally use invalid pointers.
(Anything could happen, so this can be pretty hard to debug!) Always
set pointers to NULL after freeing the object, except possibly when
the pointer is part of an object that’s just about to be destroyed.
