Enum nix::sys::signal::SigevNotify

pub enum SigevNotify {
    SigevNone,
    SigevSignal {
        signal: Signal,
        si_value: intptr_t,
    },
    SigevKevent {
        kq: RawFd,
        udata: intptr_t,

        signal: Signal,
        thread_id: type_of_thread_id,
        si_value: intptr_t,
    },
}

Used to request asynchronous notification of certain events, for example, with POSIX AIO, POSIX message queues, and POSIX timers.

Variants

SigevNone

No notification will be delivered

SigevSignal

Fields

signal: Signal

si_value: intptr_t

The signal given by signal will be delivered to the process. The value in si_value will be present in the si_value field of the siginfo_t structure of the queued signal.

SigevKevent

Fields

kq: RawFd

udata: intptr_t

A new kevent is posted to the kqueue kq. The kevent’s udata field will contain the value in udata.

SigevThreadId

Fields

signal: Signal

thread_id: type_of_thread_id

si_value: intptr_t

The signal signal is queued to the thread whose LWP ID is given in thread_id. The value stored in si_value will be present in the si_value of the siginfo_t structure of the queued signal.
