Struct PollRequest

#[repr(C)]
pub struct PollRequest<'a> { /* private fields */ }

A request for events related to a particular file descriptor in a call to poll.

Implementations

impl<'a> PollRequest<'a>

pub const fn new<'f: 'a>(file: &'f File) -> Self

Begin constructing a PollRequest that describes events to request for the given file to use in a subsequent call to poll.

The the given file must outlive the returned poll request.

pub unsafe fn events_raw(self, bitmask: c_short) -> Self

Directly set the events bitmask for this request.

Safety: The given bitmask must be a valid value for the events field of struct pollfd in the kernel’s C API.

pub unsafe fn or_events_raw(self, bitmask: c_short) -> Self

Merge the given events bitmask with the existing event bits in the object using the bitwise OR operation.

Safety: The given bitmask must be a valid value for the events field of struct pollfd in the kernel’s C API.

pub fn response(&self) -> PollResponse

Returns the result written by the latest call to poll that included this poll request object. If poll hasn’t yet been called then the response indicates that no events have occurred.
