Below is the linux_ioctl.c part of the patch of www.mpegtv.com
I really don't see anything related to SETDIR or audiocard support.
This looks to me like piece of code related to extracting audio from
CDROMs.
I checked the /sys/i386/linux/linux_ioctl.c in 3.2-stable and there I
find:
#define SETDIR(c) (((c) & ~IOC_DIRMASK) | dirbits[args->cmd >> 30])
This is: * $Id: linux_ioctl.c,v 1.30.2.8 1999/08/18 07:52:36 marcel Exp $
Am I missing something here??
