 .Dt AIO_READ 2
 .Os
 .Sh NAME
 .Nm aio_read ,
 .Nm aio_read2 ,
 .Nm aio_readv
 .Nd asynchronous read from a file (REALTIME)
 .Sh LIBRARY
 .Lb libc
 .Sh SYNOPSIS
 .In aio.h
 .Ft int
 .Fn aio_read "struct aiocb *iocb"
 .Ft int
 .Fn aio_read2 "struct aiocb *iocb" "int flags"
 .In sys/uio.h
 .Ft int
 .Fn aio_readv "struct aiocb *iocb"
 .Sh DESCRIPTION
 The
 .Fn aio_read ,
 .Fn aio_read2
 and
 .Fn aio_readv
 system calls allow the calling process to read
 from the descriptor
 .Fa iocb->aio_fildes .
 The syscalls return immediately after the read request has
 been enqueued to the descriptor; the read may or may not have
 completed at the time the call returns.
 .Pp
 For the
 .Fn aio_read
 and
 .Fn aio_readv
 calls, the read begins at the offset
 .Fa iocb->aio_offset .
 .Pp
 The
 .Fn aio_read
 call will read
 .Fa iocb->aio_nbytes
 into the buffer pointed to by
 .Fa iocb->aio_buf ,
 whereas
 .Fn aio_readv
 reads the data into the
 .Fa iocb->aio_iovcnt
 buffers specified by the members of the
 .Fa iocb->aio_iov
 array.
 For
 .Fn aio_readv
 the
 .Fa iovec
 structure is defined in
 .Xr readv 2 .
 .Pp
 The
 .Fn aio_read2
 call takes the
 .Fa flags
 argument.
 If
 .Fa flags
 is passed as zero, the call behaves identically to
 .Fn aio_read .
 The following flags can be specified by logical or:
 .Bl -tag -width AIO_OP2_VECTORED
 .It AIO_OP2_FOFFSET
 The read occurs at the file descriptor offset,
 which is advanced by the operation as done by the
 .Xr read 2
 syscall.
 The
 .Fa iocb->aio_offset
 field is ignored.
 .It AIO_OP2_VECTORED
 Similar to
 .Fn aio_readv ,
 the read buffers are specified by the
 .Fa aiocb->aio_iov
 array.
 .El
 .Pp
 The
 .Fa iocb
 pointer may be subsequently used as an argument to
 .Fn aio_return
 and
 .Fn aio_error
 in order to determine return or error status for the enqueued operation
 while it is in progress.
 .Pp
 If the request could not be enqueued (generally due to invalid arguments),
 then the call returns without having enqueued the request.
 .Pp
 If the request is successfully enqueued, the value of
 .Fa iocb->aio_offset
 can be modified during the request as context, so this value must
 not be referenced after the request is enqueued.
 .Pp
 The
 .Fa iocb->aio_sigevent
 structure can be used to request notification of the operation's
 completion as described in
 .Xr aio 4 .
 .Sh RESTRICTIONS
 The Asynchronous I/O Control Block structure pointed to by
 .Fa iocb
 and the buffer that the
 .Fa iocb->aio_buf
 member of that structure references must remain valid until the
 operation has completed.
 .Pp
 The asynchronous I/O control buffer
 .Fa iocb
 should be zeroed before the system
 calls to avoid passing bogus context information to the kernel.
 .Pp
 Modifications of the Asynchronous I/O Control Block structure or the
 buffer contents are not allowed while the request is queued.
 .Pp
 If the file offset in
 .Fa iocb->aio_offset
 is past the offset maximum for
 .Fa iocb->aio_fildes ,
 no I/O will occur.
 .Sh RETURN VALUES
 .Rv -std aio_read aio_read2 aio_readv
 .Sh DIAGNOSTICS
 None.
 .Sh ERRORS
 The
 .Fn aio_read ,
 .Fn aio_read2 ,
 and
 .Fn aio_readv
 system calls will fail if:
 .Bl -tag -width Er
 .It Bq Er EAGAIN
 The request was not queued because of system resource limitations.
 .It Bq Er EFAULT
 Part of
 .Fa aio_iov
 points outside the process's allocated address space.
 .It Bq Er EINVAL
 The asynchronous notification method in
 .Fa iocb->aio_sigevent.sigev_notify
 is invalid or not supported.
 .It Bq Er EOPNOTSUPP
 Asynchronous read operations on the file descriptor
 .Fa iocb->aio_fildes
 are unsafe and unsafe asynchronous I/O operations are disabled.
 .El
 .Pp
 The following conditions may be synchronously detected when the
 .Fn aio_read
 or
 .Fn aio_readv
 system call is made, or asynchronously, at any time thereafter.
 If they
 are detected at call time,
 The calls return -1 and set
 .Va errno
 appropriately; otherwise the
 .Fn aio_return
 system call must be called, and will return -1, and
 .Fn aio_error
 must be called to determine the actual value that would have been
 returned in
 .Va errno .
 .Bl -tag -width Er
 .It Bq Er EBADF
 The
 .Fa iocb->aio_fildes
 argument
 is invalid.
 .It Bq Er EINVAL
 The offset
 .Fa iocb->aio_offset
 is not valid, the priority specified by
 .Fa iocb->aio_reqprio
 is not a valid priority, or the number of bytes specified by
 .Fa iocb->aio_nbytes
 is not valid.
 .It Bq Er EOVERFLOW
 The file is a regular file,
 .Fa iocb->aio_nbytes
 is greater than zero, the starting offset in
 .Fa iocb->aio_offset
 is before the end of the file, but is at or beyond the
 .Fa iocb->aio_fildes
 offset maximum.
 .El
 .Pp
 If the request is successfully enqueued, but subsequently cancelled
 or an error occurs, the value returned by the
 .Fn aio_return
 system call is per the
 .Xr read 2
 system call, and the value returned by the
 .Fn aio_error
 system call is either one of the error returns from the
 .Xr read 2
 system call, or one of:
 .Bl -tag -width Er
 .It Bq Er EBADF
 The
 .Fa iocb->aio_fildes
 argument
 is invalid for reading.
 .It Bq Er ECANCELED
 The request was explicitly cancelled via a call to
 .Fn aio_cancel .
 .It Bq Er EINVAL
 The offset
 .Fa iocb->aio_offset
 would be invalid.

 .Dt AIO_WAITCOMPLETE 2
 .Os
 .Sh NAME
 .Nm aio_waitcomplete
 .Nd wait for the next completion of an aio request
 .Sh LIBRARY
 .Lb libc
 .Sh SYNOPSIS
 .In aio.h
 .Ft ssize_t
 .Fn aio_waitcomplete "struct aiocb **iocbp" "struct timespec *timeout"
 .Sh DESCRIPTION
 The
 .Fn aio_waitcomplete
 system call waits for completion of an asynchronous I/O request.
 Upon completion,
 .Fn aio_waitcomplete
 returns the result of the function and sets
 .Fa iocbp
 to point to the structure associated with the original request.
 If an asynchronous I/O request is completed before
 .Fn aio_waitcomplete
 is called, it returns immediately with the completed request.
 .Pp
 If
 .Fa timeout
 is a non-NULL pointer, it specifies a maximum interval to wait for a
 asynchronous I/O request to complete.
 If
 .Fa timeout
 is a NULL pointer,
 .Fn aio_waitcomplete
 waits indefinitely.
 To effect a poll, the
 .Fa timeout
 argument should be non-NULL, pointing to a zero-valued timeval structure.
 .Pp
 The
 .Fn aio_waitcomplete
 system call also serves the function of
 .Fn aio_return ,
 thus
 .Fn aio_return
 should not be called for the control block returned in
 .Fa iocbp .
 .Sh RETURN VALUES
 If an asynchronous I/O request has completed,
 .Fa iocbp
 is set to point to the control block passed with the original request,
 and the status is returned as described in
 .Xr read 2 ,
 .Xr write 2 ,
 or
 .Xr fsync 2 .
 On failure,
 .Fn aio_waitcomplete
 returns
 .Dv -1 ,
 sets iocbp to
 .Dv NULL
 and sets
 .Va errno
 to indicate the error condition.
 .Sh ERRORS
 The
 .Fn aio_waitcomplete
 system call fails if:
 .Bl -tag -width Er
 .It Bq Er EAGAIN
 The process has not yet called
 .Fn aio_read
 or
 .Fn aio_write .
 .It Bq Er EINTR
 A signal was delivered before the timeout expired and before any
 asynchronous I/O requests completed.
 .It Bq Er EINVAL
 The specified time limit is invalid.
 .It Bq Er EWOULDBLOCK
 .It Bq Er EINPROGRESS
 The specified time limit expired before any asynchronous I/O requests
 completed.

 .Sh DESCRIPTION
 The
 .Fn aio_write ,
 .Fn aio_write2 ,

 system calls allow the calling process to write
 to the descriptor
 .Fa iocb->aio_fildes .
 The syscalls return immediately after the write request has been enqueued
 to the descriptor; the write may or may not have completed at the time
 the call returns.

 the

 write operations append to the file in the same order as the calls were
 made.
 If
 .Dv O_APPEND
 is not set for the file descriptor, the write operation for
 .Fn aio_write
 will occur at
 the absolute position from the beginning of the file plus
 .Fa iocb->aio_offset .
 .Pp
 The
