recvmmsg and negative nread

[ethelweston]

What's the correct implementation for handling errors when using recvmmsg?

Prior to using recvmmsg, we freed the buffer immediately if nread < 0.

If we're using recvmmsg, should we continue to use this behavior or are we guaranteed to get a return with a NULL address even in the event of a transmission error?

Cheers! recvmmsg is awesome and we're very excited to use it. :-)

Yes, nread < 0 is still how you handle that. The docs could be clearer on that point. A PR improving that section would be very welcome.
