explain c++
actually, i would like to seek the answer for 'delta' when 'inter = 1'. as a c programmer, i know how the system computes the bitwise left shift operation ( 1 << inter ...) in 'start' and 'end' functions. the only thing that make me confuse is what is the purpose of term 'ldtogfxp' which stated in both functions. once i know how it works, then i think i should be able to understand how the delta value being computed. hope you can share with me some lights. thanks.
