Expand description

Returns a temporary pointer to the backing store of a JavaScript Typed Array object.

  • ctx: The execution context to use.
  • object: The Typed Array object whose backing store pointer to return.
  • 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 pointer to the raw data buffer that serves as object’s backing store or NULL if object is not a Typed Array object.

The pointer returned by this function is temporary and is not guaranteed to remain valid across JavaScriptCore API calls.
