aio_fsync - asynchronous file synchronization
Návod, kniha: Linux Programmer's Manual
#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.
- 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.
