input
INT .EXT:ref:10
is the process handle of the process to be checked.

Considerations
• CHILD_LOST_ accepts both C-series and D-series format messages. For details about the
formats of system messages, see 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. These 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.
