Hi guys,

Can someone explain me the semantic behind {read_packets, Integer} for UDP:
http://erlang.org/doc/man/inet.html

I understand the associated doc, but what i can’t get is how this option
affects me if i set it for example with:
1. {read_packets, 20} + {active, once}
2. {read_packets, 20} + {active, 100}

How many packets my process will receive in each case?

And are these packets send as multiple messages one packet at a time, or as
one message representing a list of N packets?

Thank you
/Frank
