	Memory allocation for the FFT wrapper.

static void	fnft__fft_wrapper_free (void *ptr)
	Memory deallocation for the FFT wrapper.

Detailed Description

Wraps underlying FFT library.

Wraps a FFT library (currently either KISS FFT or, if HAVE_FFTW3 is set by cmake, FFTW3). The function bodies are all declared as static inline and directly included in the header file for speed.
