       aio_fsync - asynchronous file synchronization

       Real-time library (librt, -lrt)

       #include <aio.h>

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

       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(7)), which indicates the desired type  of  asynchronous  notification  at
       completion.  All other fields are ignored.

       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.

       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.

       The aio_fsync() function is available since glibc 2.1.
