[lwip-users] issue using select() on Blackfin

[Becker, Dean]

I am trying to use the select() function prior to a recv() to avoid blocking.  I know that I have data available coming in but I cannot get the select function to recognize it.  The function times out OK but never returns anything but zero.  readset  always returns with all zeros, even if I set it to all ones before the call.  Can someone please confirm that they know this to work on the Blackfin?  My calling function looks like this:

select(maxfds+1, &readset, 0, 0, &timeout)

Thanks,

Dean
