Function rustix::fs::fsync

pub fn fsync<Fd: AsFd>(fd: Fd) -> Result<()>

Available on crate feature fs only.

fsync(fd)—Ensures that file data and metadata is written to the underlying storage device.

On iOS and macOS this isn’t sufficient to ensure that data has reached persistent storage; use fcntl_fullfsync to ensure that.
