Notes
pid_for_task est le pendant symétrique de task_for_pid : à partir d'une saveur quelconque de port task (control, read, inspect ou name), il retourne l'identifiant BSD auquel le task est lié, ou -1 / KERN_FAILURE si le port a été invalidé. C'est le pont canonique entre le côté Mach du noyau (où tout est port) et le côté BSD (où tout est PID), utilisé par libproc, sysmond, et la plupart des outils de profilage lorsqu'ils reçoivent un port task via MIG et doivent le corréler à un état façon /proc.
Détection
Aucun événement Endpoint Security. DTrace mach_trap::pid_for_task:entry est observable mais très volumineux sur les charges riches en outillage.
