How can we use the ippsFIR_Direct_16s_Sfs() function

The FIR filter function ippsFIROne_Direct_16s_Sfs() uses parameter pDlyLine and pDlyLineIndex. How can I initialize and use it ?

pt_smp and pt_smpResult are Ipp16s buffers.

Ipp16s COEFF[4]={4096, 8192, 8192, 4096};

Ipp16s *pDlyLineIndex, *pDlyLine;

pDlyLine = ippsMalloc_16s(2*4);

pDlyLineIndex = pDlyLine ;

ippsFIR_Direct_16s_Sfs(pt_smp, pt_smpResult, 64, COEFF, 32, pDlyLine, pDlyLineIndex, 0);

I would refer you to IPP manual (and particularly to ippsman.pdf) where you can find description of all IPP functions and parameters they require.
