The {\bf wxSOCKET\_BROADCAST} flag controls the use of the SO\_BROADCAST standard
setsockopt() flag. This flag allows the socket to use the broadcast address, and is generally
used in conjunction with {\bf wxSOCKET\_NOBIND} and \helpref{wxIPaddress::BroadcastAddress}{wxipaddressbroadcastaddress}.
So:
{\bf wxSOCKET\_NONE} will try to read at least SOME data, no matter how much.
