37 To link into the kernel:
40 To load as a kernel loadable module:
45 facility provides system calls for asynchronous I/O.
46 It is available both as a kernel option for static inclusion and as a
47 dynamic kernel module.
49 Asynchronous I/O control buffers should be zeroed before initializing
51 This ensures all fields are initialized.
53 All asynchronous I/O control buffers contain a
57 field which can be used to request notification when an operation completes.
62 the posted kevent will contain:
63 .Bl -column ".Va filter"
64 .It Sy Member Ta Sy Value
65 .It Va ident Ta asynchronous I/O control buffer pointer
66 .It Va filter Ta Dv EVFILT_AIO
69 .Va aio_sigevent.sigev_value
77 the information for the queued signal will include
81 field and the value stored in
82 .Va sigevent.sigev_value
91 .Va aio_sigevent.sigev_value
93 .Va aio_sigevent.sigev_notify_function
