/**
* @class OFDDPSocket OFDDPSocket.h ObjFW/OFDDPSocket.h
*
* @brief A class which provides methods to create and use AppleTalk DDP
* sockets.
*
* Addresses are of type @ref OFSocketAddress. You can use
* @ref OFSocketAddressMakeAppleTalk to create an address or
* @ref OFSocketAddressAppleTalkNetwork to get the AppleTalk network,
* @ref OFSocketAddressAppleTalkNode to get the AppleTalk node and
* @ref OFSocketAddressAppleTalkPort to get the port (sometimes also called
* socket number).
*
* @note On some systems, packets received with the wrong protocol type just
* get filtered by the kernel, however, on other systems, the packet is
* queued up and will raise an @ref OFReadFailedException with the
* @ref OFReadFailedException#errNo set to `ENOMSG` when being received.
*
* @warning Even though the OFCopying protocol is implemented, it does *not*
* return an independent copy of the socket, but instead retains it.
* This is so that the socket can be used as a key for a dictionary,
* so context can be associated with a socket. Using a socket in more
* than one thread at the same time is not thread-safe, even if copy
* was called to create one "instance" for every thread!
