i was just going to post those myself. Funny thing is, according to the article, this has been available since the 2.2 kernel version but it isn't in the device driver development book (oreilly) In any case I am looking for a similar component for FreeBSD. And if there isn't a precise match what would the closest way be to get that functionality? ---jdp On Tue, 4 Nov 2008, Nikolay Denev wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > > On 4 Nov, 2008, at 17:50 , Alfred Perlstein wrote: > >> * Joe Pellegrino <jdp@elvis.rowan.edu> [081103 16:30] wrote: >>> I am trying to develop a small kernel module and I wanted to ask some >>> questions about implementation.
