Open a socket of the given type. The family argument specifies the
address family; it defaults to AF_INET. The type argument specifies
whether this is a stream (SOCK_STREAM, this is the default)
or datagram (SOCK_DGRAM) socket. The protocol argument defaults to 0,
2012-12-10 14:56:05 -08:00
specifying the default protocol. Keyword arguments are accepted.
2012-12-02 19:56:17 -08:00
A socket object represents one endpoint of a network connection.
2012-12-10 14:56:05 -08:00
Methods of socket objects (keyword arguments not allowed):
2012-12-02 19:56:17 -08:00
accept() -- accept a connection, returning new socket and client address
bind(addr) -- bind the socket to a local address
close() -- close the socket
connect(addr) -- connect the socket to a remote address
connect_ex(addr) -- connect, return an error code instead of an exception
2012-12-10 14:56:05 -08:00
dup() -- return a new socket object identical to the current one [*]
2012-12-02 19:56:17 -08:00
fileno() -- return underlying file descriptor
getpeername() -- return remote address [*]
getsockname() -- return local address
2012-12-10 14:56:05 -08:00
getsockopt(level, optname[, buflen]) -- get socket options
2012-12-02 19:56:17 -08:00
gettimeout() -- return timeout or None
2012-12-10 14:56:05 -08:00
listen(n) -- start listening for incoming connections
2012-12-02 19:56:17 -08:00
makefile([mode, [bufsize]]) -- return a file object for the socket [*]
recv(buflen[, flags]) -- receive data
recv_into(buffer[, nbytes[, flags]]) -- receive data (into a buffer)
recvfrom(buflen[, flags]) -- receive data and sender's address
recvfrom_into(buffer[, nbytes, [, flags])
-- receive data and sender's address (into a buffer)
sendall(data[, flags]) -- send all data
2012-12-10 14:56:05 -08:00
send(data[, flags]) -- send data, may not send all of it
2012-12-02 19:56:17 -08:00
sendto(data[, flags], addr) -- send data to a given address
setblocking(0 | 1) -- set or clear the blocking I/O flag
2012-12-10 14:56:05 -08:00
setsockopt(level, optname, value) -- set socket options
2012-12-02 19:56:17 -08:00
settimeout(None | float) -- set or clear the timeout
shutdown(how) -- shut down traffic in one or both directions
2012-12-10 14:56:05 -08:00
2012-12-02 19:56:17 -08:00
[*] not available on all platforms!
Wait for an incoming connection. Return a new socket representing the
connection, and the address of the client. For IP sockets, the address
2012-12-10 14:56:05 -08:00
info is a pair (hostaddr, port).
2012-12-02 19:56:17 -08:00
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).
2012-12-10 14:56:05 -08:00
2012-12-02 19:56:17 -08:00
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).
Returns the timeout in seconds (float) associated with socket
operations. A timeout of None indicates that timeouts on socket
2012-12-10 14:56:05 -08:00
operations are disabled.
2012-12-02 19:56:17 -08:00
Set a socket option. See the Unix manual for level and option.
The value argument can either be an integer or a string.
Get a socket option. See the Unix manual for level and option.
2012-12-10 14:56:05 -08:00
If a nonzero buffersize argument is given, the return value is a
2012-12-02 19:56:17 -08:00
string of that length; otherwise it is an integer.
Bind the socket to a local address. For IP sockets, the address is a
pair (host, port); the host must refer to the local host. For raw packet
2012-12-10 14:56:05 -08:00
sockets the address is a tuple (ifname, proto [,pkttype [,hatype]])
2012-12-02 19:56:17 -08:00
Close the socket. It cannot be used after this call.
2012-12-10 14:56:05 -08:00
2012-12-02 19:56:17 -08:00
Connect the socket to a remote address. For IP sockets, the address
is a pair (host, port).
This is like connect(address), but returns an error code (the errno value)
instead of raising an exception when an error occurs.
2012-12-10 14:56:05 -08:00
Return the integer file descriptor of the socket.
2012-12-02 19:56:17 -08:00
2012-12-10 14:56:05 -08:00
Return the address of the local endpoint. For IP sockets, the address
2012-12-02 19:56:17 -08:00
info is a pair (hostaddr, port).
Return the address of the remote endpoint. For IP sockets, the address
info is a pair (hostaddr, port).
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.
Receive up to buffersize bytes from the socket. For the optional flags
2012-12-10 14:56:05 -08:00
argument, see the Unix manual. When no data is available, block until
2012-12-02 19:56:17 -08:00
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. ¸
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
2012-12-10 14:56:05 -08:00
is not specified (or 0), receive up to the size available in the given buffer.
2012-12-02 19:56:17 -08:00
2012-12-10 14:56:05 -08:00
See recv() for documentation about the flags.
2012-12-02 19:56:17 -08:00
2012-12-10 14:56:05 -08:00
Like recv(buffersize, flags) but also return the sender's address info. ¸
2012-12-02 19:56:17 -08:00
2012-12-10 14:56:05 -08:00
Like recv_into(buffer[, nbytes[, flags]]) but also return the sender's address info.
2012-12-02 19:56:17 -08:00
2012-12-10 14:56:05 -08:00
Send a data string to the socket. For the optional flags
2012-12-02 19:56:17 -08:00
argument, see the Unix manual. Return the number of bytes
sent; this may be less than len(data) if the network is busy.
2012-12-10 14:56:05 -08:00
2012-12-02 19:56:17 -08:00
Send a data string to the socket. For the optional flags
2012-12-10 14:56:05 -08:00
argument, see the Unix manual. This calls send() repeatedly
2012-12-02 19:56:17 -08:00
until all data is sent. If an error occurs, it's impossible
to tell how much data has been sent.
2012-12-10 14:56:05 -08:00
2012-12-02 19:56:17 -08:00
Like send(data, flags) but allows specifying the destination address.
2012-12-10 14:56:05 -08:00
For IP sockets, the address is a pair (hostaddr, port).
2012-12-02 19:56:17 -08:00
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).
Control the socket with WSAIoctl syscall. Currently supported 'cmd' values are
SIO_RCVALL: 'option' must be one of the socket.RCVALL_* constants.
SIO_KEEPALIVE_VALS: 'option' is a tuple of (onoff, timeout, interval). � ‡ � d � d � Ť � ‹ � � ’ � – � c � c � c �
2012-12-10 14:56:05 -08:00
2012-12-02 19:56:17 -08:00
Return the current host name.
2012-12-10 14:56:05 -08:00
Return the IP address (a string of the form '255.255.255.255') for a host.
