Cuse4BSD + Webcamd + FE_GET_EVENT ioctl

[Hans Petter Selasky]

int fd_frontend = DvbOpen(DEV_DVB_FRONTEND, adapter, frontend, O_RDWR |
O_NONBLOCK); -----
So for me it looks like O_NONBLOCK is set and used but it still hangs at
the ioctl.

Make sure the flag is also received by webcamd. Maybe there is a bug there.

Any other ideas?
Kind regards

Could you compile webcamd with -g and run it from gdb. Then dump all threads
when it is hanging?

If you meant hitting Ctrl-C in gdb and running 'thread apply all bt' in
gdb, i've done this and will send you the results off-list.
