## API
|
||
|
|
|
||
|
|
### allocUnsafe(size)
|
||
|
|
|
||
|
|
- `size` <Integer> The desired length of the new `Buffer`
|
||
|
|
|
||
|
|
Allocates a new *non-zero-filled* `Buffer` of `size` bytes. The `size` must be
|
||
|
|
less than or equal to the value of `buffer.kMaxLength` and greater than or equal
|
||
|
|
to zero. Otherwise, a `RangeError` is thrown.
