AIO_FSYNC(3)               Linux Programmer’s Manual              AIO_FSYNC(3)



NAME
       aio_fsync - asynchronous file synchronization

SYNOPSIS
       #include <aio.h>

       int aio_fsync(int op, struct aiocb *aiocbp);


DESCRIPTION
       The  aio_fsync  function does a sync on all outstanding asynchronous I/O operations
       associated with aiocbp->aio_fildes.

       More precisely, if op is O_SYNC, then all currently queued I/O operations shall  be
       completed as if by a call of fsync(2), and if op is O_DSYNC, this call is the asyn-
       chronous analog of fdatasync(2).  Note that this is a request only - this call does
       not wait for I/O completion.

       Apart  from aio_fildes the only field in the structure pointed to by aiocbp that is
       used by this call is the aio_sigevent field (a struct sigevent) that indicates  the
       desired  type  of  asynchronous  notification  at completion.  All other fields are
       ignored.

RETURN VALUE
       On success (the sync request was successfully queued) this function returns  0.  On
       error -1 is returned, and errno is set appropriately.

ERRORS
       EAGAIN Out of resources.

       EBADF  aio_fildes is not a valid file descriptor open for writing.

       EINVAL No  synchronized  I/O  for  this  file  is supported, or op is not O_SYNC or
              O_DSYNC.

CONFORMING TO
       POSIX 1003.1-2003
