See the socket module for documentation. 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. 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. if_indextoname(if_index)
Returns the interface name corresponding to the interface index if_index. if_nametoindex(if_name)
Returns the interface index corresponding to the interface name if_name. if_nameindex()
Returns a list of network interface information (index, name) tuples. setdefaulttimeout(timeout)
Set the default timeout in seconds (float) for new socket objects.
A value of None indicates that new socket objects have no timeout.
When the socket module is first imported, the default is None. getdefaulttimeout() -> timeout
Returns the default timeout in seconds (float) for new socket objects.
A value of None indicates that new socket objects have no timeout.
When the socket module is first imported, the default is None. getnameinfo(sockaddr, flags) --> (host, port)
Get host and port for a sockaddr. getaddrinfo(host, port [, family, type, proto, flags])
-> list of (family, type, proto, canonname, sockaddr)
Resolve host and port into addrinfo struct. inet_ntop(af, packed_ip) -> string formatted IP address
Convert a packed IP address of the given family to string format. inet_pton(af, ip) -> packed IP address string
Convert an IP address from string format to a packed string suitable
for use with low-level network functions. inet_ntoa(packed_ip) -> ip_address_string
Convert an IP address from 32-bit packed binary format to string format inet_aton(string) -> bytes giving packed 32-bit IP representation
Convert an IP address in string format (123.45.67.89) to the 32-bit packed
binary format used in low-level network functions. htonl(integer) -> integer
Convert a 32-bit integer from host to network byte order. htons(integer) -> integer
Convert a 16-bit unsigned integer from host to network byte order.
Note that in case the received integer does not fit in 16-bit unsigned
integer, but does fit in a positive C int, it is silently truncated to
16-bit unsigned integer.
However, this silent truncation feature is deprecated, and will raise an
exception in future versions of Python. ntohl(integer) -> integer
Convert a 32-bit integer from network to host byte order. ntohs(integer) -> integer
Convert a 16-bit unsigned integer from network to host byte order.
Note that in case the received integer does not fit in 16-bit unsigned
integer, but does fit in a positive C int, it is silently truncated to
16-bit unsigned integer.
However, this silent truncation feature is deprecated, and will raise an
exception in future versions of Python. socketpair([family[, type [, proto]]]) -> (socket object, socket object)
Create a pair of socket objects from the sockets returned by the platform
socketpair() function.
The arguments are the same as for socket() except the default family is
AF_UNIX if defined on the platform; otherwise, the default is AF_INET. dup(integer) -> integer
Duplicate an integer socket file descriptor. This is like os.dup(), but for
sockets; on some platforms os.dup() won't work for socket file descriptors. close(integer) -> None
Close an integer socket file descriptor. This is like os.close(), but for
sockets; on some platforms os.close() won't work for socket file descriptors. getprotobyname(name) -> integer
Return the protocol number for the named protocol. (Rarely used.) getservbyport(port[, protocolname]) -> string
Return the service name from a port number and protocol name.
The optional protocol name, if given, should be 'tcp' or 'udp',
otherwise any protocol will match. getservbyname(servicename[, protocolname]) -> integer
Return a port number from a service name and protocol name.
The optional protocol name, if given, should be 'tcp' or 'udp',
otherwise any protocol will match. gethostbyaddr(host) -> (name, aliaslist, addresslist)
Return the true host name, a list of aliases, and a list of IP addresses,
for a host. The host argument is a string giving a host name or IP number. gethostbyname_ex(host) -> (name, aliaslist, addresslist)
Return the true host name, a list of aliases, and a list of IP addresses,
for a host. The host argument is a string giving a host name or IP number. gethostbyname(host) -> address
Return the IP address (a string of the form '255.255.255.255') for a host. sethostname(name)
Sets the hostname to name. gethostname() -> string
Return the current host name. 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). sendmsg_afalg([msg], *, op[, iv[, assoclen[, flags=MSG_MORE]]])
Set operation mode, IV and length of associated data for an AF_ALG
operation socket. 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 bytes-like 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 bytes-like 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(data[, flags], address) -> count
Like send(data, flags) but allows specifying the destination address.
For IP sockets, the address is a pair (hostaddr, port). 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. 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. 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. 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. recvfrom_into(buffer[, nbytes[, flags]]) -> (nbytes, address info)
Like recv_into(buffer[, nbytes[, flags]]) but also return the sender's address info. recvfrom(buffersize[, flags]) -> (data, address info)
Like recv(buffersize, flags) but also return the sender's address info. 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. 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. listen([backlog])
Enable a server to accept connections. If backlog is specified, it 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. If not specified, a default reasonable value is chosen. getpeername() -> address info
Return the address of the remote endpoint. For IP sockets, the address
info is a pair (hostaddr, port). getsockname() -> address info
Return the address of the local endpoint. For IP sockets, the address
info is a pair (hostaddr, port). fileno() -> integer
Return the integer file descriptor of the socket. connect_ex(address) -> errno
This is like connect(address), but returns an error code (the errno value)
instead of raising an exception when an error occurs. connect(address)
Connect the socket to a remote address. For IP sockets, the address
is a pair (host, port). detach()
Close the socket object without closing the underlying file descriptor.
The object cannot be used after this call, but the file descriptor
can be reused for other purposes. The file descriptor is returned. close()
Close the socket. It cannot be used after this call. bind(address)
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
sockets the address is a tuple (ifname, proto [,pkttype [,hatype [,addr]]]) getsockopt(level, option[, buffersize]) -> value
Get a socket option. See the Unix manual for level and option.
If a nonzero buffersize argument is given, the return value is a
string of that length; otherwise it is an integer. setsockopt(level, option, value: int)
setsockopt(level, option, value: buffer)
setsockopt(level, option, None, optlen: int)
Set a socket option. See the Unix manual for level and option.
The value argument can either be an integer, a string buffer, or
None, optlen. gettimeout() -> timeout
Returns the timeout in seconds (float) associated with socket
operations. A timeout of None indicates that timeouts on socket
operations are disabled. 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). getblocking()
Returns True if socket is in blocking mode, or False if it
is in non-blocking mode. 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). _accept() -> (integer, address info)
Wait for an incoming connection. Return a new socket file descriptor
representing the connection, and the address of the client.
For IP sockets, the address info is a pair (hostaddr, port). 6e socket(family=AF_INET, type=SOCK_STREAM, proto=0) -> socket object
socket(family=-1, type=-1, proto=-1, fileno=None) -> socket object
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,
specifying the default protocol. Keyword arguments are accepted.
The socket is created as non-inheritable.
When a fileno is passed in, family, type and proto are auto-detected,
unless they are explicitly set.
A socket object represents one endpoint of a network connection.
