> I thought that the low level scsi i/o routines did just that io with > ioctls... The low-level SCSI I/O routines need a freeform I/O approach, and they're designed for casual poking at things in an out-of-band fashion, sort of like a SCSI geek-port. Luigi's hack is for CDDA (sucking audio off the CD) acccess; this is basically bulk data transfer. Being a read-like operation, it's better handled as such. With a little more work, once you support audio accesses in the driver properly, you become able to produce a "cdrom audio FS", where tracks on the disk appear as files when the disk is mounted. I appreciate that Luigi's hack is expedient, and as I said if there's a strong precedent (ie. binary compatability issues) then sure, we should support it. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
