Re: [ASL] Error in select

Hi Dhaval,

It's been a very long time since I've looked at my ad-hoc stuff...so I=20=

don't recall exactly what the problem was.

But looking at the source code in aodv.cc, the call to select() does=20
not seem correct.  select() needs a struct timeval * as its last=20
argument, so I think you should declare a struct timeval timeout , and=20=

initialize the timeout.tv_sec and timeout.tv_usec fields of, and then=20
pass this pointer to this to select().  The existing aodv.cc just=20
passes a NULL pointer, which select() might be complaining about (and=20
thus returning < 0).

That may be the problem. Let me (or this list) know.  When I get back=20
into this work, I'll look at it some more.

I also plan to take a crack at figuring out why route_check doesn't=20
want to work in kernels > 2.4.18, now that I've been learning a bit=20
about linux kernel internals.  Ah, the todo list keeps getting bigger.=20=

:)

Hope this helps,
