aio_fsync: asynchronous file synchronization
aio_fsync - asynchronous file synchronization
int aio_fsync(int op, struct aiocb *aiocbp);
DESCRIPTIONThe 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.)
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.
RETURN VALUEOn success (the sync request was successfully queued) this function returns 0. On error, -1 is returned, and errno is set appropriately.
- Out of resources.
- aio_fildes is not a valid file descriptor open for writing.
- Synchronized I/O is not supported for this file, or op is not O_SYNC or O_DSYNC.
- aio_fsync() is not implemented.
VERSIONSThe aio_fsync() function is available since glibc 2.1.
