Hi all,
I am trying to capture read events on tun0 device on freeBSD 5.5 using
libevent library v1.2. But the event_dispatch() function returns with
an error "Operation not supported by device".
Is /dev/tun0 device supported by libevent 1.2?
libevent doesn't do anything differently than you'd do by directly
using kqueue(), poll(), or select() system calls. I know at least
select() works on FreeBSD's tun0 device, since tinc uses it.
You might try:
* looking through tinc's code for some device-specific setup you're
missing
* checking what actual system called failed with ktrace
* testing each mechanism:
$ EVENT_SHOW_METHOD= ./test
(should say kqueue)
$ EVENT_SHOW_METHOD= EVENT_NOKQUEUE= ./test
(should say poll)
$ EVENT_SHOW_METHOD= EVENT_NOKQUEUE= EVENT_NOPOLL= ./test
(should say select)
