<p>This function will return the data pointer attached to the object <code>obj</code> stored using the string key <code>key</code>. If the object is valid and data was stored under the given key, the pointer that was stored will be reuturned. If this is not the case, NULL will be returned, signifying an invalid object or non-existent key. It is possible a NULL pointer was stored given that key, but this situation is non-sensical and thus can be considered an error as well. NULL pointers are never stored as this is the return value if an error occurs.</p>
