18// UDPSocket
19// Accessor API for a UDP socket in either client or server form.
20//
21// Client form:
22// In this case, we're connecting to a specific server, so the client will
23// usually use:
24//       Connect(address)    // Connect to a UDP server
25//       Read/Write          // Reads/Writes all go to a single destination
26//
27// Server form:
28// In this case, we want to read/write to many clients which are connecting
29// to this server.  First the server 'binds' to an addres, then we read from
30// clients and write responses to them.
31// Example:
32//       Bind(address/port)  // Binds to port for reading from clients
33//       RecvFrom/SendTo     // Each read can come from a different client
34//                           // Writes need to be directed to a specific
35//                           // address.
