| |
Does anyone have ideas how to preserve a /proc/$pid directory after a process exit? I want to perform some audit on some process A from within another process B. Process B have the pid of process A but after A exit, B can no longer retrieve info from /proc/$pid. I am wondering whether it is possible for B to have a special "handle" of /proc/$pid so that after A exist B can still read from it.
In my situation, A know nothing of B so A can send no message to B.
Are there any mechanism for this purpose? Locking that dir?
Thanks, Yubin
