Struct nix::sys::signal::SigEvent

#[repr(C)]
pub struct SigEvent { /* fields omitted */ }

Used to request asynchronous notification of the completion of certain events, such as POSIX AIO and timers.

Methods

impl SigEvent

pub fn new(sigev_notify: SigevNotify) -> SigEvent

Note: this constructor does not allow the user to set the sigev_notify_kevent_flags field. That's considered ok because on FreeBSD at least those flags don't do anything useful. That field is part of a union that shares space with the more genuinely useful fields.

Note: This constructor also doesn't allow the caller to set the sigev_notify_function or sigev_notify_attributes fields, which are required for SIGEV_THREAD. That's considered ok because on no operating system is SIGEV_THREAD the most efficient way to deliver AIO notification. FreeBSD and DragonFly BSD programs should prefer SIGEV_KEVENT. Linux, Solaris, and portable programs should prefer SIGEV_THREAD_ID or SIGEV_SIGNAL. That field is part of a union that shares space with the more genuinely useful sigev_notify_thread_id
