Function ptr

ptr(view: TypedArray | ArrayBufferLike | DataView, byteOffset?: number): number
Get the pointer backing a TypedArray or ArrayBuffer

Use this to pass TypedArray or ArrayBuffer to C functions.

This is for use with FFI functions. For performance reasons, FFI will not automatically convert typed arrays to C pointers.

Example
From JavaScript:
```
const array = new Uint8Array(10);
const rawPtr = ptr(array);
myFFIFunction(rawPtr);
```
To C:
```
void myFFIFunction(char* rawPtr) {
 // Do something with rawPtr
}
```
Parameters
- view: TypedArray | ArrayBufferLike | DataView
  
  the typed array or array buffer to get the pointer for
- Optional byteOffset: number
  
  optional offset into the view in bytes
Returns number
