    JsGetTypedArrayStorage(
    _In_ JsValueRef typedArray,
    _Outptr_result_bytebuffer_(*bufferLength) BYTE **buffer,
    _Out_ unsigned int *bufferLength,

    _Out_opt_ int *elementSize);

• typedArray: The typed array instance.
• buffer: The array's buffer. The lifetime of the buffer returned is the same as the lifetime of the the array. The buffer pointer does not count as a reference to the array for the purpose of garbage collection.
• bufferLength: The number of bytes in the buffer.
• arrayType: The type of the array.
• elementSize: The size of an element of the array.

The code JsNoError if the operation succeeded, a failure code otherwise.
