a HANDLE from CreateEvent was used for signaling, both within a process and across processes.
WaitableEvent is the cross platform replacement for this. To convert:
* HANDLE -> base::WaitableEvent*
* ScopedHandle -> scoped_ptr<base::WaitableEvent>
* CreateEvent -> new base::WaitableEvent
* SetEvent -> base::WaitableEvent::Signal
* ResetEvent -> base::WaitableEvent::Reset
* ObjectWatcher -> base::WaitableEventWatcher
* WaitForMultipleObjects -> static base::WaitableEvent::WaitMany
ObjectWatcher remains for Windows specific code. WaitableEventWatcher has an identical interface save,
* It uses WaitableEvents, not HANDLEs
* It returns void from StartWatching and StopWatcher, rather than errors. System internal errors are fatal to the address space
IMPORTANT: There are semantic differences between the different platforms. WaitableEvents on Windows are implemented on top of events. Windows events work across process and this is used mostly for modal dialog support. Windows events can be duplicated with DuplicateHandle.
On other platforms, WaitableEvent works only within a single process. In the future we shall have to replace the current uses of cross-process events with IPCs.
BEWARE: HANDLE, on Windows, is a void *. Since any pointer type coerces to void *, you can pass a WaitableEvent * where a HANDLE is expected without any build-time errors.
