function writev
Usage in Deno
```typescript import { writev } from "node:node__fs.d.ts"; ```
writev(fd: number,buffers: readonly ArrayBufferView[],cb: (err: ErrnoException | null,bytesWritten: number,buffers: ArrayBufferView[],) => void,): void
Write an array of `ArrayBufferView`s to the file specified by `fd` using `writev()`.
`position` is the offset from the beginning of the file where this data
should be written. If `typeof position !== 'number'`, the data will be written
at the current position.
The callback will be given three arguments: `err`, `bytesWritten`, and `buffers`. `bytesWritten` is how many bytes were written from `buffers`.
If this method is `util.promisify()` ed, it returns a promise for an `Object` with `bytesWritten` and `buffers` properties.
It is unsafe to use `fs.writev()` multiple times on the same file without
waiting for the callback. For this scenario, use [createWriteStream](../.././node__fs.d.ts/~/createWriteStream).
On Linux, positional writes don't work when the file is opened in append mode.
The kernel ignores the position argument and always appends the data to
the end of the file.
