Edit Question
Title
Body
Pretty basic question here, I'm a little unsure on the passing around of memory in C. If I have the following CGPoint* tileForCoordinates (CGPoint position, short width, short height) { CGPoint *tileCoordinate = (CGPoint*)malloc(sizeof(CGPoint)); tileCoordinate->xTile = (position.xPosition / width); tileCoordinate->yTile = (position.yPosition / height); return tileCoordinate; } and I wanted to call this in another source file or whatever, would I declare a pointer and above and return it? If so, When I call is from another class e.g. CGPoint *currentTilePosition = tileForCoordinates(curPosition, 50, 50); What happens to the pointer returned by malloc? Should it be freed or whats the story? :)
