NAME

       aio_fsync - asynchronous file synchronization

LIBRARY

       Real-time library (librt, -lrt)

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.  (See aio(7) for a description of the aiocb structure.)

       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 asynchronous analog of fdatasync(2).

       Note that this is a request only; it 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 sigevent structure, described in sigevent(3type)), which 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 to indicate the error.

ERRORS

       EAGAIN Out of resources.

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

       EINVAL Synchronized I/O is not supported for this file, or op is not O_SYNC or O_DSYNC.

       ENOSYS aio_fsync() is not implemented.
