[vdr] Getting the Frontend File Descriptor from a plugin.

["Are Årseth" <are@arseth.org>]

Is there a recomended way to access the frontend of the cDvbDevice using
the plugin interface? I'm trying to make a Signal / Noise plugin, but the
only way I was able to access the frontend was if I patched the
dvbdevice.h with a getFrontend() function. Thats not very elegant :)

My current somewhat working, but very ugly code is here:
http://www.arseth.org/php/vdr-snr-0.0.1.tgz

And the patch to dvbdevice is:
diff -c vdr-1.1.20_clean/dvbdevice.c vdr-1.1.20/dvbdevice.c
