+/**
+ * Function:  omxSP_FFTGetBufSize_C_FC32
+ *
+ * Description:
+ * These functions compute the size of the specification structure
+ * required for the length 2^order complex FFT and IFFT functions. The function
+ * <FFTGetBufSize_C_FC32> is used in conjunction with the 32-bit functions
+ * <FFTFwd_CToC_FC32_Sfs> and <FFTInv_CToC_FC32_Sfs>.
+ *
+ * Input Arguments:
+ *
+ *   order - base-2 logarithm of the desired block length; valid in the range
+ *            [1,12] ([1,15] if BIG_FFT_TABLE is defined.)
+ *
+ * Output Arguments:
+ *
+ *   pSize - pointer to the number of bytes required for the specification
+ *            structure
+ *
+ * Return Value:
+ *
+ *    OMX_Sts_NoErr - no error
+ *
+ *
