 care to avoid unwanted reentrance.
 

+The {\bf wxSOCKET\_REUSEADDR} flag controls the use of the SO\_REUSEADDR standard
+setsockopt() flag. This flag allows the socket to bind to a port that is already in use.
+This is mostly used on UNIX-based systems to allow rapid starting and stopping of a server - 
+otherwise you may have to wait several minutes for the port to become available.
+wxSOCKET\_REUSEADDR can also be used with socket clients to (re)bind to a particular local port
+for an outgoing connection.
+This option can have surprising platform dependent behavior, so check the documentation for
+your platform's implementation of setsockopt(). Note that on BSD-based systems (e.g. Mac OS X),
+use of wxSOCKET\_REUSEADDR implies SO\_REUSEPORT in addition to SO\_REUSEADDR to be consistent
+with Windows.
+
+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}.
