Expand description

Creates a JavaScript Typed Array object from an existing JavaScript Array Buffer object with the given offset and length.

  • ctx: The execution context to use.
  • arrayType: A value identifying the type of array to create. If arrayType is JSTypedArrayType::None or JSTypedArrayType::ArrayBuffer then NULL will be returned.
  • buffer: An Array Buffer object that should be used as the backing store for the created JavaScript Typed Array object.
  • byteOffset: The byte offset for the created Typed Array. byteOffset should aligned with the element size of arrayType.
  • length: The number of elements to include in the Typed Array.
  • exception: A pointer to a JSValueRef in which to store an exception, if any. Pass NULL if you do not care to store an exception.

Returns a JSObjectRef that is a Typed Array or NULL if there was an error. The backing store of the Typed Array will be buffer.
