FileHandle.writev - node__fs--promises.d.ts - Node

method FileHandle.writev

Usage in Deno

```typescript import { type FileHandle } from "node:node__fs--promises.d.ts"; ```



FileHandle.writev(buffers: readonly ArrayBufferView[],
position?: number,
): Promise<WriteVResult>

Write an array of [ArrayBufferView](https://developer.mozilla.org/en-US/docs/Web/API/ArrayBufferView) s to the file. The promise is fulfilled with an object containing a two properties: It is unsafe to call `writev()` multiple times on the same file without waiting for the promise to be fulfilled (or rejected). 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.

Parameters



buffers: readonly ArrayBufferView[]

optional



position: number = 'null'

The offset from the beginning of the file where the data from `buffers` should be written. If `position` is not a `number`, the data will be written at the current position.

Return Type

Promise<WriteVResult>
