When a UNIX process initiates one or more dependent processes, we call these child processes, or children. Child and parent processes have the same user ID.
Select a process entry in the Process Manager scrolling pane.
Choose Trace Children from the Process menu.
Process Manager displays a record of the creation of any new children (and their children, recursively) for the selected process.
Error returns are reported using the error code names described in the Intro(2) man page.
The equivalent UNIX command is:
truss -fa -texec,fork -s¦CLD,ALRM -p PID
where PID is the process ID of the selected process.
