I my realmode library I used it too and it was faster than int 10h function,
but Shawn said that he measured under protmode DJGPP and the int was lot
faster. This of course may depend quite a lot on his card or configuration.
May be the reflecting of ints is better in CWSDPMI? 

BTW I don't see any reason for writing just another library, maybe just to
practice coding.
