+.SH NAME
+aio_fsync \- asynchronous file synchronization
+.SH LIBRARY
+Real-time library
+.RI ( librt ", " \-lrt )
+.SH SYNOPSIS
+.nf
+.B "#include <aio.h>"
+.PP
+.BI "int aio_fsync(int " op ", struct aiocb *" aiocbp );
+.fi
+.SH DESCRIPTION
+The
+.BR aio_fsync ()
+function does a sync on all outstanding asynchronous I/O operations
+associated with
+.IR aiocbp\->aio_fildes .
+(See
+.BR aio (7)
+for a description of the
+.I aiocb
+structure.)
+.PP
+More precisely, if
+.I op
+is
+.BR O_SYNC ,
+then all currently queued I/O operations shall be
+completed as if by a call of
+.BR fsync (2),
+and if
+.I op
+is
+.BR O_DSYNC ,
+this call is the asynchronous analog of
+.BR fdatasync (2).
+.PP
+Note that this is a request only; it does not wait for I/O completion.
+.PP
+Apart from
+.IR aio_fildes ,
+the only field in the structure pointed to by
+.I aiocbp
+that is used by this call is the
+.I aio_sigevent
+field (a
+.I sigevent
+structure, described in
+.BR sigevent (7)),
+which indicates the desired type of asynchronous notification at completion.
+All other fields are ignored.
+.SH RETURN VALUE
+On success (the sync request was successfully queued)
+this function returns 0.
+On error, \-1 is returned, and
+.I errno
+is set to indicate the error.
+.SH ERRORS
+.TP
+.B EAGAIN
+Out of resources.
+.TP
+.B EBADF
+.I aio_fildes
+is not a valid file descriptor open for writing.
+.TP
+.B EINVAL
+Synchronized I/O is not supported for this file, or
+.I op
+is not
+.B O_SYNC
+or
+.BR O_DSYNC .
+.TP
+.B ENOSYS
+.BR aio_fsync ()
+is not implemented.
