Where kqueue() is available, this is used, otherwise poll(). The poll() implementation is less comprehensive and rather more limited. - -To add a compatible object, call Add(). To remove it, call Remove(). To wait for an object to become ready, call Wait(), which returns a pointer to the first ready object, or 0 for a timeout. - -The timeout is set either in the constructor, or using the SetTimout() method. It is specified in milliseconds. - -The kqueue based implementation will automatically remove objects when they are closed (actually, the OS does this), but the poll implementation requires that Remove() be called. - -The flags passed to Add() or Remove() are passed to the object, and are ignored by this class. - -For an object to be able to be added to the list, it should implement FillInKEvent() and FillInPoll() for kqueue and poll implementations respectively. Use the PLATFORM_KQUEUE_NOT_SUPPORTED define to test which is necessary for the platform. - -It does not have to be derived off any particular class, as it uses templates to be compatible with any class. - |
