Summary
The CHILD_LOST_ procedure examines a system message to determine whether it
indicates that a specified process or process pair has been lost.
When a process receives a system message on $RECEIVE, it can call CHILD_LOST_
to determine whether the message contains information indicating that a particular
process has been deleted or has been lost due to a processor or system failure.
CHILD_LOST_ reports a loss if any of the following are true:
•
The connection to a remote system has been lost and the specified process was
running in that system.
•
A local or remote processor has failed and the specified process was running in
that processor.
•
A process deletion message has been received for the specified unnamed
process, for the specified single named process, or for the entire named process
pair of which the specified process is a member.
