+/** |
+ * 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 |
+ * |
+ * |
