Here is an excerpt from a yet-unpublished change to my Concurrency chapter:
-----
The OwnerTerminated and LinkTerminated exceptions can be received as
messages as well. The following code demonstrates this for the
OwnerTerminated exception:
bool isDone = false;
while (!isDone) {
receive(
(int message)
{
writeln("Message: ", message);
}
,
(OwnerTerminated exc)
{
writeln("The owner has terminated; exiting.");
isDone = true;
}
);
}
-----
In order to receive LinkTerminated as a message, start the worker with
spawnLinked() instead of spawn().
