aio_fsync - asynchronous file synchronization
int aio_fsync(int op, struct aiocb *aiocbp);
Link with -lrt
() function does a sync on all outstanding asynchronous I/O
operations associated with aiocbp->aio_fildes
. (See aio
for a description of the aiocb
More precisely, if op
, then all currently queued I/O
operations shall be completed as if by a call of fsync
(2), and if
, this call is the asynchronous analog of
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
that is used by this call is the aio_sigevent
structure, described in sigevent
(7)), which indicates
the desired type of asynchronous notification at completion. All other fields
On 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.
() function is available since glibc 2.1.
