Attempts to cancel an iocb previously passed to io_submit. Attempts to cancel an iocb previously passed to io_submit. If the operation is successfully cancelled, the resulting event is copied into the memory pointed to by result without being placed into the completion queue and 0 is returned. May fail with -EFAULT if any of the data structures pointed to are invalid. May fail with -EINVAL if aio_context specified by ctx_id is invalid. May fail with -EAGAIN if the iocb specified was not cancelled. Will fail with -ENOSYS if not implemented.
Destroy the aio_context specified. May cancel any outstanding AIOs and block on completion. Will fail with -ENOSYS if not implemented. May fail with -EINVAL if the context pointed to is invalid.
Attempts to read at least min_nr events and up to nr events from the completion queue for the aio_context specified by ctx_id. If it succeeds, the number of read events is returned. May fail with -EINVAL if ctx_id is invalid, if min_nr is out of range, if nr is out of range, if timeout is out of range. May fail with -EFAULT if any of the memory specified is invalid. May return 0 or < min_nr if the timeout specified by timeout has elapsed before sufficient events are available, where timeout == NULL specifies an infinite timeout. Note that the timeout pointed to by timeout is relative. Will fail with -ENOSYS if not implemented.
read asynchronous I/O events from the completion queue
Create an asynchronous I/O context. Create an aio_context capable of receiving at least nr_events. ctxp must not point to an aio_context that already exists, and must be initialized to 0 prior to the call. On successful creation of the aio_context, *ctxp is filled in with the resulting handle. May fail with -EINVAL if *ctxp is not initialized, if the specified nr_events exceeds internal limits. May fail with -EAGAIN if the specified nr_events exceeds the user’s limit of available events. May fail with -ENOMEM if insufficient kernel resources are available. May fail with -EFAULT if an invalid pointer is passed for ctxp. Will fail with -ENOSYS if not implemented.
Queue the nr iocbs pointed to by iocbpp for processing. Returns the number of iocbs queued. May return -EINVAL if the aio_context specified by ctx_id is invalid, if nr is < 0, if the iocb at *iocbpp[0] is not properly initialized, if the operation specified is invalid for the file descriptor in the iocb. May fail with -EFAULT if any of the data structures point to invalid data. May fail with -EBADF if the file descriptor specified in the first iocb is invalid. May fail with -EAGAIN if insufficient resources are available to queue any iocbs. Will return 0 if nr is 0. Will fail with -ENOSYS if not implemented.
