[lwip-devel] Netconn callback order

[Bill Florac]

Is there a reason why the callback from netconn_new_with_callback() must occur 
before the data is put into the mailbox rather than after (recv_udp() function 
in api_msg.c)?  I would like to make the receiving of packets (UDP) event based 
rather than have to poll and wait for them.  If the callback occurs after the 
posting then I could get the data from the callback. Or, better yet, pass a 
pointer to the netbuf in the callback and return a flag if the data has been 
eaten skipping the mailbox all together.
