I was wondering about something:
LazyFoo, the author of some amazing SDL tutorials has put copyright on his source code. Does this prevent people from writing functions that are largely, if not entirely similar to his? For example, his 'load_image' function used in a lot of the tutorials is extremely useful. Does the copyright prevent me from using this function, or one very similar to it in my own code and then posting it online, on say - this forum?
