GL> is that a correct assumption? not that i know. perl doesn't track child processes. that is done by the user code and the OS. and the OS never kills a process, it can only let them be killed and then reaped by some other process. if a parent dies and its child later exits, that will get reaped by the process 0 (or id 1?) usually called init. it is the parent of all processes (first process after boot) and it will reap any child it sees. a zombie process happens when a child die and its parent is still not dead but hasn't reaped the child. use the open pipe idea for full control over the child, its output and reaping it. uri -- Uri Guttman -- uri AT perlhunter DOT com --- http://www.perlhunter.com -- ------------ Perl Developer Recruiting and Placement Services ------------- ----- Perl Code Review, Architecture, Development, Training, Support ------- _______________________________________________ Boston-pm mailing list [email protected] http://mail.pm.org/mailman/listinfo/boston-pm
