 /**
+ * Function:  omxSP_FFTFwd_CToC_FC32_Sfs   (2.2.4.2.2)
+ *
+ * Description:
+ * Compute an FFT for a complex signal of length of 2^order, 
+ * where 0 <= order <= 15. 
+ * Transform length is determined by the specification structure, which 
+ * must be initialized prior to calling the FFT function using the appropriate 
+ * helper, i.e., <FFTInit_C_sc32> or <FFTInit_C_SC16>. The relationship 
+ * between the input and output sequences can be expressed in terms of the 
+ * DFT, i.e., 
+ *
+ *      X[k] = SUM[n=0...N-1]x[n].e^(-jnk.2.pi/N)
+ *      k = 0,1,2,..., N-1
+ *      N = 2^order
+ *
+ * Input Arguments:
+ *   pSrc - pointer to the input signal, a complex-valued vector of length
+ *            2^order; must be aligned on a 32 byte boundary. 
+ *   pFFTSpec - pointer to the preallocated and initialized specification 
+ *            structure 
+ *
+ * Output Arguments:
+ *   pDst - pointer to the complex-valued output vector, of length 2^order;
+ *            must be aligned on an 32-byte boundary. 
+ *
+ * Return Value:
+ *    
+ *    OMX_Sts_NoErr - no error 
+ *    OMX_Sts_BadArgErr - returned if one or more of the following conditions 
+ *              is true: 
+ *    -   one or more of the following pointers is NULL: pSrc, pDst, or 
+ *              pFFTSpec. 
+ *    -    pSrc or pDst is not 32-byte aligned 
+ *    -    scaleFactor<0 or scaleFactor >32
