pub fn aio_cancel_all(fd: RawFd) -> Result<AioCancelStat>
Cancels outstanding AIO requests for a given file descriptor.
Examples
Issue an aio operation, then cancel all outstanding operations on that file descriptor.
let wbuf = b"CDEF"; let mut f = tempfile().unwrap(); let mut aiocb = AioCb::from_slice( f.as_raw_fd(), 2, //offset &wbuf[..], 0, //priority SigevNotify::SigevNone, LioOpcode::LIO_NOP); aiocb.write().unwrap(); let cs = aio_cancel_all(f.as_raw_fd()).unwrap(); if cs == AioCancelStat::AioNotCanceled { while (aiocb.error() == Err(Error::from(Errno::EINPROGRESS))) { thread::sleep(time::Duration::from_millis(10)); } } // Must call `aio_return`, but ignore the result let _ = aiocb.aio_return();
