[linux-dvb] FE_GET_EVENT to clear frontend event queue: only for QPSK?

[Nico Sabbi <nsabbi@tiscali.it>]

Hi,
of the current ?zap applications only szap uses FE_GET_EVENT to clear 
the event queue before tuning;
tzap and czap don't.
Is there a particular reason for this? Clearing an event queue seems to 
be a reasonably common
thing to do.

Besides, some user reported in mplayer-dvb ML that this particular 
ioctl() seems to block tuning
when used in some usb -t frontends, even though the frontend is opened 
in non blocking mode.

Can someone explain, please?

Thanks,
      Nico
