@function @abstract Returns a temporary pointer to the backing store of a JavaScript Typed Array object. @param ctx The execution context to use. @param object The Typed Array object whose backing store pointer to return. @param 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. @result A pointer to the raw data buffer that serves as object’s backing store or NULL if object is not a Typed Array object. @discussion The pointer returned by this function is temporary and is not guaranteed to remain valid across JavaScriptCore API calls.
