synchronous vs. asynchronous messages

[Gary Wessle]

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.
