They `Set the [interrupt] Priority Level'. Get a good book about Unix kernels, e.g. ``The 4.4BSD Operating System. Design and Implementation.'' for an explanation about spl's. Or wait until i will have transformed Bruce Evans' formal description of them into the man page spl(9). However, while the book is already available right now, i don't make any promises for when the man page will be ready. ;-) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
