-/* Socket module */
-
-/*
-
-This module provides an interface to Berkeley socket IPC.
-
-Limitations:
-
-- Only AF_INET, AF_INET6 and AF_UNIX address families are supported in a
-  portable manner, though AF_PACKET and AF_NETLINK are supported under Linux.
-- No read/write operations (use sendall/recv or makefile instead).
-- Additional restrictions apply on some non-Unix platforms (compensated
-  for by socket.py).
-
-Module interface:
-
-- socket.error: exception raised for socket specific errors
-- socket.gaierror: exception raised for getaddrinfo/getnameinfo errors,
-	a subclass of socket.error
-- socket.herror: exception raised for gethostby* errors,
-	a subclass of socket.error
-- socket.fromfd(fd, family, type[, proto]) --> new socket object (created
-        from an existing file descriptor)
-- socket.gethostbyname(hostname) --> host IP address (string: 'dd.dd.dd.dd')
-- socket.gethostbyaddr(IP address) --> (hostname, [alias, ...], [IP addr, ...])
-- socket.gethostname() --> host name (string: 'spam' or 'spam.domain.com')
-- socket.getprotobyname(protocolname) --> protocol number
-- socket.getservbyname(servicename[, protocolname]) --> port number
-- socket.getservbyport(portnumber[, protocolname]) --> service name
-- socket.socket([family[, type [, proto]]]) --> new socket object
-- socket.socketpair([family[, type [, proto]]]) --> (socket, socket)
-- socket.ntohs(16 bit value) --> new int object
-- socket.ntohl(32 bit value) --> new int object
-- socket.htons(16 bit value) --> new int object
-- socket.htonl(32 bit value) --> new int object
-- socket.getaddrinfo(host, port [, family, socktype, proto, flags])
-	--> List of (family, socktype, proto, canonname, sockaddr)
-- socket.getnameinfo(sockaddr, flags) --> (host, port)
-- socket.AF_INET, socket.SOCK_STREAM, etc.: constants from <socket.h>
-- socket.has_ipv6: boolean value indicating if IPv6 is supported
-- socket.inet_aton(IP address) -> 32-bit packed IP representation
-- socket.inet_ntoa(packed IP) -> IP address string
-- socket.getdefaulttimeout() -> None | float
-- socket.setdefaulttimeout(None | float)
-- an Internet socket address is a pair (hostname, port)
-  where hostname can be anything recognized by gethostbyname()
-  (including the dd.dd.dd.dd notation) and port is in host byte order
-- where a hostname is returned, the dd.dd.dd.dd notation is used
-- a UNIX domain socket address is a string specifying the pathname
-- an AF_PACKET socket address is a tuple containing a string
-  specifying the ethernet interface and an integer specifying
-  the Ethernet protocol number to be received. For example:
-  ("eth0",0x1234).  Optional 3rd,4th,5th elements in the tuple
-  specify packet-type and ha-type/addr.
-
-Local naming conventions:
-
-- names starting with sock_ are socket object methods
-- names starting with socket_ are module-level functions
-- names starting with PySocket are exported through socketmodule.h

-Open a socket of the given type.  The family argument specifies the\n\
