Re: Timing Under MiNT



There is also a Tmalarm call for millisecond resolution, but you should keep
in mind that MiNT's signal handling does not guarantee real-time response.

  Hi....

  In case anyone missed it ;) I'm working on the XaAES AES replacement for
  MiNT. I've got a problem, and thought someone might be able to help.

  At the moment I use Talarm() to set timer callbacks in order to implement
  evnt_timer() and evnt_multi(MU_TIMER). This works fine (there's a delta queue
  backing up the signal handler to allow multiple events), but the problem
  is the Talarm() only has a resolution of 1 second, which is to long for
  several apps (notably Yukon calls evnt_timer() in between dealing each card
  - with a minimum 1sec delay, dealling a full deck takes ages).

  I think I should implement my own clock device (write a time in milliseconds,
  select on it and it will write back after n millisecond) - can anyone give me
  a few pointers on devices (I don't really have time to work it out myself, as
  there is still a fair bit of XaAES to finish).

  Craig.
