Socket objects. You construct a socket using the socket procedure, passing an address family af/* constant for family (IPv4, IPv6) and a socket type sock/* constant for socket type (TCP, UDP). protocol should almost always be zero, unless you are creating raw sockets; it is implicit in the socket type. Sockets take up a file descriptor in the system until closed, which may or may not happen automatically on error. All sockets are created in non-blocking mode.
- The socket's file descriptor.
- The socket family, an integer constant.
- The socket type, an integer constant.
- The socket protocol, an integer constant.
Note that sockets are also implicitly created by socket-connect/ai and socket-accept.
