    Regarding Event mechanism

    Dear OpenKODE team,

    First of all thank to all who have been a part of the development of OpenKODE..

    Let me know about the khronos Grp view point on the following:

    How will be the OpenKODE event mechanism coexists with other existing event mechanism ?
    Is it necessary that all the applications in the system should use the OpeKODE event mechanism and system mechanism as a gateway by making the existing mechanism as its subset?

    Would like to discuss on that....

    Hi

    Just to clarify: OpenKODE is intended to specify how one application in one process works, and does not say anything about interaction of different processes/applications.

    A typical OpenKODE implementation sits on top of facilities provided by the underlying OS. So OpenKODE events usually come from events in the OS's event system.

    Therefore other non-OpenKODE applications continue to work as they would, and the OS's event system works as normal.

    I am confused, isn't threading optionally supported in openKode? BTW, how is threading implemented? and what is the threading model? is there a soft memory copy or a hard one, does the system spawn or does it use lightweight processes for threading?

    Are you guys talking about some sort of IPC communication?

    Yes, OpenKODE does have threading. The model is a subset of POSIX threads. Each thread has its own event queue; for events from a window, socket or timer, OpenKODE posts the event to the queue for the thread that created the window, socket or timer.
