## API |
|
|
|
### alloc(size[, fill[, encoding]]) |
|
|
|
- `size` <Integer> The desired length of the new `Buffer` |
|
- `fill` <String> | <Buffer> | <Integer> A value to pre-fill the new `Buffer` with. **Default:** `0` |
|
- `encoding` <String> If `fill` is a string, this is its encoding. **Default:** `'utf8'` |
|
|
|
Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the `Buffer` will be zero-filled. |
