This module provides socket operations and some related functions.
On Unix, it supports IP (Internet Protocol) and Unix domain sockets.
On other systems, it only supports IP. Functions specific for a
socket are available as methods of the socket object.
 
Functions:
 
socket() -- create a new socket object
socketpair() -- create a pair of new socket objects [*]
fromfd() -- create a socket object from an open file descriptor [*]
fromshare() -- create a socket object from data received from socket.share() [*]
gethostname() -- return the current hostname
gethostbyname() -- map a hostname to its IP number
gethostbyaddr() -- map an IP number or hostname to DNS info
getservbyname() -- map a service name and a protocol name to a port number
getprotobyname() -- map a protocol name (e.g. 'tcp') to a number

inet_ntoa() -- convert 32-bit packed format IP to string (123.45.67.89)
socket.getdefaulttimeout() -- get the default timeout value
socket.setdefaulttimeout() -- set the default timeout value
create_connection() -- connects to an address, with an optional timeout and
                       optional source address.
 
 [*] not available on all platforms!
 
Special objects:
 
SocketType -- type object for socket objects
error -- exception raised for I/O errors
has_ipv6 -- boolean value indicating if IPv6 is supported
 
Integer constants:
 
AF_INET, AF_UNIX -- socket domains (first argument to socket() call)
SOCK_STREAM, SOCK_DGRAM, SOCK_RAW -- socket types (second argument)
 
Many other constants may be defined; these may be used in calls to
the setsockopt() and getsockopt() methods.

If a nonzero buffersize argument is given, the return value is a string of that length; otherwise it is an integer. gettimeout(...) gettimeout() -> timeout   Returns the timeout in seconds (float) associated with socket  operations. A timeout of None indicates that timeouts on socket  operations are disabled. listen(...) listen(backlog)   Enable a server to accept connections.  The backlog argument must be at least 0 (if it is lower, it is set to 0); it specifies the number of unaccepted connections that the system will allow before refusing new connections. recv(...) recv(buffersize[, flags]) -> data   Receive up to buffersize bytes from the socket.  For the optional flags argument, see the Unix manual.  When no data is available, block until at least one byte is available or until the remote end is closed.  When the remote end is closed and all data is read, return the empty string. recv_into(...) recv_into(buffer, [nbytes[, flags]]) -> nbytes_read   A version of recv() that stores its data into a buffer rather than creating  a new string.  Receive up to buffersize bytes from the socket.  If buffersize  is not specified (or 0), receive up to the size available in the given buffer.   See recv() for documentation about the flags. recvfrom(...) recvfrom(buffersize[, flags]) -> (data, address info)   Like recv(buffersize, flags) but also return the sender's address info. recvfrom_into(...) recvfrom_into(buffer[, nbytes[, flags]]) -> (nbytes, address info)   Like recv_into(buffer[, nbytes[, flags]]) but also return the sender's address info. recvmsg(...) recvmsg(bufsize[, ancbufsize[, flags]]) -> (data, ancdata, msg_flags, address)   Receive normal data (up to bufsize bytes) and ancillary data from the socket.  The ancbufsize argument sets the size in bytes of the internal buffer used to receive the ancillary data; it defaults to 0, meaning that no ancillary data will be received.  Appropriate buffer sizes for ancillary data can be calculated using CMSG_SPACE() or CMSG_LEN(), and items which do not fit into the buffer might be truncated or discarded.  The flags argument defaults to 0 and has the same meaning as for recv().   The return value is a 4-tuple: (data, ancdata, msg_flags, address). The data item is a bytes object holding the non-ancillary data received.  The ancdata item is a list of zero or more tuples (cmsg_level, cmsg_type, cmsg_data) representing the ancillary data (control messages) received: cmsg_level and cmsg_type are integers specifying the protocol level and protocol-specific type respectively, and cmsg_data is a bytes object holding the associated data.  The msg_flags item is the bitwise OR of various flags indicating conditions on the received message; see your system documentation for details.  If the receiving socket is unconnected, address is the address of the sending socket, if available; otherwise, its value is unspecified.   If recvmsg() raises an exception after the system call returns, it will first attempt to close any file descriptors received via the SCM_RIGHTS mechanism. recvmsg_into(...) recvmsg_into(buffers[, ancbufsize[, flags]]) -> (nbytes, ancdata, msg_flags, address)   Receive normal data and ancillary data from the socket, scattering the non-ancillary data into a series of buffers.  The buffers argument must be an iterable of objects that export writable buffers (e.g. bytearray objects); these will be filled with successive chunks of the non-ancillary data until it has all been written or there are no more buffers.  The ancbufsize argument sets the size in bytes of the internal buffer used to receive the ancillary data; it defaults to 0, meaning that no ancillary data will be received.  Appropriate buffer sizes for ancillary data can be calculated using CMSG_SPACE() or CMSG_LEN(), and items which do not fit into the buffer might be truncated or discarded.  The flags argument defaults to 0 and has the same meaning as for recv().   The return value is a 4-tuple: (nbytes, ancdata, msg_flags, address). The nbytes item is the total number of bytes of non-ancillary data written into the buffers.  The ancdata item is a list of zero or more tuples (cmsg_level, cmsg_type, cmsg_data) representing the ancillary data (control messages) received: cmsg_level and cmsg_type are integers specifying the protocol level and protocol-specific type respectively, and cmsg_data is a bytes object holding the associated data.  The msg_flags item is the bitwise OR of various flags indicating conditions on the received message; see your system documentation for details.  If the receiving socket is unconnected, address is the address of the sending socket, if available; otherwise, its value is unspecified.   If recvmsg_into() raises an exception after the system call returns, it will first attempt to close any file descriptors received via the SCM_RIGHTS mechanism. send(...) send(data[, flags]) -> count   Send a data string to the socket.  For the optional flags argument, see the Unix manual.  Return the number of bytes sent; this may be less than len(data) if the network is busy. sendall(...) sendall(data[, flags])   Send a data string to the socket.  For the optional flags argument, see the Unix manual.  This calls send() repeatedly until all data is sent.  If an error occurs, it's impossible to tell how much data has been sent. sendmsg(...) sendmsg(buffers[, ancdata[, flags[, address]]]) -> count   Send normal and ancillary data to the socket, gathering the non-ancillary data from a series of buffers and concatenating it into a single message.  The buffers argument specifies the non-ancillary data as an iterable of buffer-compatible objects (e.g. bytes objects). The ancdata argument specifies the ancillary data (control messages) as an iterable of zero or more tuples (cmsg_level, cmsg_type, cmsg_data), where cmsg_level and cmsg_type are integers specifying the protocol level and protocol-specific type respectively, and cmsg_data is a buffer-compatible object holding the associated data.  The flags argument defaults to 0 and has the same meaning as for send().  If address is supplied and not None, it sets a destination address for the message.  The return value is the number of bytes of non-ancillary data sent. sendto(...) sendto(data[, flags], address) -> count   Like send(data, flags) but allows specifying the destination address. For IP sockets, the address is a pair (hostaddr, port). setblocking(...) setblocking(flag)   Set the socket to blocking (flag is true) or non-blocking (false). setblocking(True) is equivalent to settimeout(None); setblocking(False) is equivalent to settimeout(0.0). setsockopt(...) setsockopt(level, option, value)   Set a socket option.  See the Unix manual for level and option. The value argument can either be an integer or a string. settimeout(...) settimeout(timeout)   Set a timeout on socket operations.  'timeout' can be a float, giving in seconds, or None.  Setting a timeout of None disables the timeout feature and is equivalent to setblocking(1). Setting a timeout of zero is the same as setblocking(0). shutdown(...) shutdown(flag)   Shut down the reading side of the socket (flag == SHUT_RD), the writing side of the socket (flag == SHUT_WR), or both ends (flag == SHUT_RDWR).

		CMSG_LEN(...) CMSG_LEN(length) -> control message length   Return the total length, without trailing padding, of an ancillary data item with associated data of the given length.  This value can often be used as the buffer size for recvmsg() to receive a single item of ancillary data, but RFC 3542 requires portable applications to use CMSG_SPACE() and thus include space for padding, even when the item will be the last in the buffer.  Raises OverflowError if length is outside the permissible range of values. CMSG_SPACE(...) CMSG_SPACE(length) -> buffer size   Return the buffer size needed for recvmsg() to receive an ancillary data item with associated data of the given length, along with any trailing padding.  The buffer space needed to receive multiple items is the sum of the CMSG_SPACE() values for their associated data lengths.  Raises OverflowError if length is outside the permissible range of values. create_connection(address, timeout=
