CHILD_LOST_ Procedure
Considerations
•
CHILD_LOST_ accepts both C-series and D-series format messages. For details
about the formats of system messages, refer to the
Guardian Procedure Errors
and Messages Manual.
•
CHILD_LOST_ determines whether a process has been lost by comparing the
process or process pair designated in the system message with the process that is
specified in the
processhandle parameter. The following tables show the
comparison that is made for each system message for each type of process
specified by
processhandle. If the comparison shown in the table is true, the
process has been lost.
