Question

I am looking for something analogous to CreateEvent(), SetEvent() and WaitForMultipleObjects() from the Win32 world.

Specifically this has to be accessible across processes on the same machine.

We are already using Poco for some cross platform stuff, but I don’t see that the Poco::Event is what I want. perhaps i am missing something.

EDIT:

To explain what I want to do:

I want process B to know when something happens in process A. This is trivial in win32 – Each process/thread calls CreateEvent() with a name for the event. Process B calls waitForXObject() and Process A calls SetEvent() when something happens. B is signaled.

Again, this is trivial in win32, but how to do it cross-platform.

Answer 1

There is no built in way in C++ to do named events. But you can use boost to do it.

You’re looking for boost::condition and boost::named_condition

As you also mentioned there exists: Poco.NamedEvent
