Howto obtain sysfs-pathes for DVB devices?

Hello again,

now I've managed to obtain syfs-pathes for v4l2-devices. But what about dvb? I haven't found something like bus_info in the dvb-api-docs. (I'm new to it) Any hints for this?

Thanks,
Carsten

I'm also still new on it ...

Maybe anything useful here?

cat /sys/class/dvb/dvb0.frontend0/uevent MAJOR=212
MINOR=0 PHYSDEVPATH=/devices/pci0000:00/0000:00:08.0/0000:01:07.0 PHYSDEVBUS=pci
PHYSDEVDRIVER=saa7134

Hi,

IMHO there is no other way (not counting other daemons) than scanning the dvb-device-files, stat() them, and compare major and minor numbers with sysfs-contents. Anyway, I think I'll switch to HAL for that...

One way of asking udev is this:
udevadm info -q path -n /dev/dvb/adapter0/frontend0

Ok, then I think I'm gonna use it... :) It's much more simple than struggling through dbus-/hal-libs and the various unfinished c++ bindings, although I normally don't like to start system-tools from c++. Or is there any c-api for it? I haven't found one.
