Struct nix::sys::event::Kqueue

#[repr(transparent)]
pub struct Kqueue(_);

Available on crate feature event only.

A kernel event queue.

Used by the kernel to notify the process of various types of asynchronous events.

Implementations

impl Kqueue

pub fn new() -> Result<Self>

Create a new kernel event queue.

pub fn kevent( &self, changelist: &[KEvent], eventlist: &mut [KEvent], timeout_opt: Option<timespec> ) -> Result<usize>

Register new events with the kqueue, and return any pending events to the user.

This method will block until either the timeout expires, or a registered event triggers a notification.

Arguments

• changelist - Any new kevents to register for notifications.
• eventlist - Storage space for the kernel to return notifications.
• timeout - An optional timeout.

Returns

Returns the number of events placed in the eventlist. If an error occurs while processing an element of the changelist and there is enough room in the eventlist, then the event will be placed in the eventlist with EV_ERROR set in flags and the system error in data.

Trait Implementations
