I think the answer is 'it depends'. - such prototypes are not required by C99. - using (void) is part of some authors' style and not of others. For the latter, this is not an 'oversight' but an uglification. - in some cases the omission is deliberate as the function is used for variable sets of arguments (e.g, in GraphicsDevice.h). - in others the omission is because it seemed safer to leave the prototype out than to get it wrong (when passing functions, for example). - some code is taken from other projects and still has K&R style declarations.
