Struct nix::sys::signal::SigEvent

source ·
#[repr(C)]
pub struct SigEvent { sigevent: sigevent, }
Expand description

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

Fields§

§sigevent: sigevent

Implementations§

source§

impl SigEvent

source

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

source

pub fn sigevent(&self) -> sigevent

Return a copy of the inner structure

source

pub fn as_mut_ptr(&mut self) -> *mut sigevent

Returns a mutable pointer to the sigevent wrapped by self

impl PartialEq for SigEvent

source§

fn eq(&self, other: &SigEvent) -> bool

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
