[asio-users] UDP - maximum receive size

[Gheorghe M. <ghe...@gm...>]

Hi,

I send requests to a name server for name resolution. It's not clear for me
how can I tell when the receiving of data on the client socket has ended.
When I call "async_receive " on the socket I begin reading data from
server. Will asio call my receive completed handler (along with data on my
buffer) only when it has
detected that all the datagram has been received   (that is for *one call*
to async_receive function) or is it possible to get that handler called
multiple times as it happens with tcp (do I have to call async receive
multiple times in this case?)

Also what is the effect on setting option receive buffer size on asio ? Any
thoughts are appreciated.
