There isn't one. It's either q_atomic_test_and_set_ptr or 
QBasicAtomicPointer::testAndSet.

If your use-cases don't need to be thread-safe, you can do it like this:

#define K_GLOBAL_STATIC_NOT_THREADSAFE(TYPE, NAME) 	\
	static TYPE *this_NAME;				\
	static void delete_NAME()			\
	{						\
		delete this_NAME;			\
		this_NAME = 0;				\
	}						\
							\
	static TYPE *NAME()			 	\
	{						\
		if (!this_NAME) {			\
			this_NAME = new TYPE;		\
			qAddPostRoutine(delete_NAME));	\
		}					\
		return this_NAME;			\
	}
