# BNNSCreateRandomGenerator(_:_:)

Returns a new random number generator using an internally generated random seed.

## Declaration

```swift
func BNNSCreateRandomGenerator(_ method: BNNSRandomGeneratorMethod, _ filter_params: UnsafePointer<BNNSFilterParameters>?) -> BNNSRandomGenerator?
```

## Parameters

- `method`: The method that the generator uses to generate random numbers.
- `filter_params`: The filter runtime parameters.

## Return Value

Return Value A pointer to the random generator.
