# Buffer Fill
|
|
|
|
A [ponyfill](https://ponyfill.com) for `Buffer.fill`.
|
|
|
|
Works as Node.js: `v6.4.0` <br>
|
|
Works on Node.js: `v0.10.0`
|
|
|
|
## Installation
|
|
|
|
```sh
|
|
npm install --save buffer-fill
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const fill = require('buffer-fill')
|
|
const buf = Buffer.allocUnsafe(5)
|
|
|
|
console.log(buf.fill(8))
|
|
//=> <Buffer 08 08 08 08 08>
|
|
|
|
console.log(buf.fill(9, 2, 4))
|
|
//=> <Buffer 08 08 09 09 08>
|
|
|
|
console.log(buf.fill('linus', 'latin1'))
|
|
//=> <Buffer 6c 69 6e 75 73>
|
|
|
|
console.log(buf.fill('\u0222'))
|
|
//=> <Buffer c8 a2 c8 a2 c8>
|
|
```

## API
|
|
|
|
### fill(buf, value[, offset[, end]][, encoding])
|
|
|
|
- `value` <String> | <Buffer> | <Integer> The value to fill `buf` with
|
|
- `offset` <Integer> Where to start filling `buf`. **Default:** `0`
|
|
- `end` <Integer> Where to stop filling `buf` (not inclusive). **Default:** `buf.length`
|
|
- `encoding` <String> If `value` is a string, this is its encoding. **Default:** `'utf8'`
|
|
- Return: <Buffer> A reference to `buf`
|
|
|
|
Fills `buf` with the specified `value`. If the `offset` and `end` are not given,
|
|
the entire `buf` will be filled. This is meant to be a small simplification to
|
|
allow the creation and filling of a `Buffer` to be done on a single line.
|
|
|
|
If the final write of a `fill()` operation falls on a multi-byte character, then
|
|
only the first bytes of that character that fit into `buf` are written.
