Expand description

Information lue depuis un signalfd (un signalfd_siginfo).

Layout C parsé par le wrapper depuis le buffer kernel ; les champs non-pertinents pour le signal reçu sont à 0/None côté kernel.

Fields§

§signal: Signal

§errno: i32

si_errno (rarement utilisé).

§code: i32

si_code (origine du signal : SI_USER, SI_KERNEL, CLD_EXITED, …).

§pid: Option<Pid>

si_pid : PID expéditeur. None si l’origine est le kernel (0).

§uid: u32

si_uid : UID expéditeur.

§fd: i32

ssi_fd : FD source pour les signaux liés à un I/O (SIGIO).

§timer_id: u32

ssi_tid : ID du timer (spec Air : timer_id).

§band: u32

ssi_band : pour SIGIO.

§overrun: u32

ssi_overrun : nombre d’overruns timer.

§trap_no: u32

ssi_trapno : pour SIGTRAP.

§status: i32

ssi_status : pour SIGCHLD (code de sortie ou signal fatal).

§int: i32

ssi_int : entier attaché pour SI_QUEUE-style.

§ptr: u64

ssi_ptr : pointeur attaché pour SI_QUEUE-style.

§utime: u64
