### Method

# JavaScriptCore Value new_typed_array_with_buffer

since: 2.38

#### Declaration [src]

    JSCValue*
    jsc_value_new_typed_array_with_buffer (
      JSCValue* array_buffer,
      JSCTypedArrayType type,
      gsize offset,
      gssize length
    )

#### Description [src]

Create a new typed array value with elements from an array buffer.

Create a `JSCValue` referencing a new typed array value containing elements of the given `type`, where the elements are stored at the memory region represented by the `array_buffer`.

The `type` must not be `JSC_TYPED_ARRAY_NONE`.

The `offset` and `length` parameters can be used to indicate which part of the array buffer can be accessed through the typed array. If both are omitted (passing zero as `offset`, and `-1` as `length`), the whole `array_buffer` is exposed through the typed array. Omitting the `length` with a non-zero `offset` will expose the remainder of the `array_buffer` starting at the indicated offset.

Available since: 2.38

#### Parameters

`type`

  Type: `JSCTypedArrayType`

  Type of array elements.

`offset`

  Type: `gsize`

  Offset, in bytes.

`length`

  Type: `gssize`

  Number of array elements, or `-1`.

#### Return value

Type: `JSCValue`

A `JSCValue`.

The caller of the method takes ownership of the data, and is responsible for freeing it.
