pub unsafe extern "C" fn cef_v8_value_create_array_buffer_with_copy(
    buffer: *mut c_void,
    length: usize,
) -> *mut cef_v8_value_t

Create a new cef_v8_value_t object of type ArrayBuffer which copies the provided |buffer| of size |length| bytes. This function should only be called from within the scope of a cef_render_process_handler_t, cef_v8_handler_t or cef_v8_accessor_t callback, or in combination with calling enter() and exit() on a stored cef_v8_context_t reference.
