  Do not use this function. It has been superseded by arm_cfft_f32 and will be removed in the future.
  Parameters

    [in] | *S | points to an instance of the floating-point Radix-2 CFFT/CIFFT structure.
    [in,out] | *pSrc | points to the complex data buffer of size `2*fftLen`. Processing occurs in-place.

  Returns
    none.
