ippsFFTInit -- allocation and deallocation of the FFT specification structure

The first argument of ippsFFTInit is a double pointer to the FFT specification structure to be created.
Do I need to call ippsFree() on *ppFFTSpec when I am done using it?

IppStatus ippsFFTInit_C_64f(IppsFFTSpec_C_64f** ppFFTSpec, int order, int flag, IppHintAlgorithm hint, Ipp8u* pSpec, Ipp8u* pSpecBuffer);

Thanks
