cbuffersegm_interpolate() Cbuffer * cbuffersegm_interpolate ( const Cbuffer *  start, const Cbuffer *  end, long double  ratio  ) Return a circular buffer interpolated from a circular buffer segment with respect to a fraction of its total length. Parameters [in] start,end Circular buffers defining the segment [in] ratio Float in [0,1] representing the fraction of the total length of the segment for locating the interpolated circular buffer
