time question

[Bart Vandewoestyne <Bart.Vandewoestyne@pandora.be>]

I'm trying to port the DOS driver for a data aquisition card to linux
(http::/mc303.ulyssis.org).  It is my first linux driver writing
attempt. Somewhere in the code i have the following lines of DOS-code
that do some busy waiting:

_bios_timeofday(_TIME_GETCLOCK,&tb); l = tb;
  while(l-tb < 2) _bios_timeofday(_TIME_GETCLOCK,&l);

What is the best linux equivalent for this?

Thanks,
mc303
