Struct nix::sys::signal::SigEvent
#[repr(C)]
pub struct SigEvent { /* fields hidden */ }
Documentation
Used to request asynchronous notification of the completion of certain events, such as POSIX AIO and timers.
Implementations
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
pub fn sigevent(&Self) -> libc::sigevent
Return a copy of the inner structure
