In some cases, an application must use one or more socket options or ioctls in order to operate, as in the case of AppleTalk or IrDA. Even so, an application will most likely use only a few options at a time. Of course, one of the more frustrating aspects of socket options and ioctls is that not all options or ioctls are available on every Windows platform, causing trouble for those applications that are attempting to be cross-platform-compatible.
