NAME aio_fsync - asynchronous file synchronization
SYNOPSIS #include <aio.h> int aio_fsync(int op, struct aiocb *aiocbp); Link with -lrt.
DESCRIPTION The aio_fsync() function does a sync on all outstanding asynchronous I/O operations asso‐ ciated 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 com‐ pleted 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.
RETURN VALUE On success (the sync request was successfully queued) this function returns 0. On error, -1 is returned, and errno is set appropriately.
ERRORS 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.
VERSIONS The aio_fsync() function is available since glibc 2.1.
