aio_fsync − asynchronous file synchronization
#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.
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 — 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.
On success (the sync request was successfully queued) this function returns 0. On error −1 is returned, and errno is set appropriately.
