Let us start again with our positive intentions in tact :) Thanks for the clarification of system.c - that's not to say that I'll never ask of it again, but I think I have a good grasp of it now. >>Given the application that your current random number generator is used >>for, the code which you have, although an impressive generator, is (imho) >>unnecessarily complex and memory hungry. > >You may be correct.

I will dig deep and see what I can find. Speak soon, BC Received on 2003-04-09 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
