    Hi

    what is the difference between synchronous vs. asynchronous messages
    an object sends to another.
    google was not much of a friend and wikipedia did not come to the
    rescue.

    thanks

    Wrong newsgroup. Standard C++ does not discuss synchronous or
    asynchronous messages.

    very simplistic example.....(and follow up set to comp.object)

    Synchronous : when the caller has to wait for the callee to finish
    processing the message.

    Asynchronous: Where the Event Generator sends out an Event Object,
    which contains all necessary info about what happened. The event is
    sent out to an Event Queue (usually on a different thread or indeed in
    a different process) and the Even Consumer(S) all handle as required.
