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

When\n| the remote end is closed and all data is read, return the empty string.\n|\n| recvinto(...)\n| recvinto(buffer, [nbytes[, flags]]) -> nbytesread\n|\n| A version of recv() that stores its data into a buffer rather than creating\n| a new string. Receive up to buffersize bytes from the socket. If buffersize\n| is not specified (or 0), receive up to the size available in the given buffer.\n|\n| See recv() for documentation about the flags.\n|\n| recvfrom(...)\n| recvfrom(buffersize[, flags]) -> (data, address info)\n|\n| Like recv(buffersize, flags) but also return the sender's address info.\n|\n| recvfrominto(...)\n| recvfrominto(buffer[, nbytes[, flags]]) -> (nbytes, address info)\n|\n| Like recvinto(buffer[, nbytes[, flags]]) but also return the sender's address info.\n|\n| recvmsg(...)\n| recvmsg(bufsize[, ancbufsize[, flags]]) -> (data, ancdata, msgflags, address)\n|\n| Receive normal data (up to bufsize bytes) and ancillary data from the\n| socket. The ancbufsize argument sets the size in bytes of the\n| internal buffer used to receive the ancillary data; it defaults to 0,\n| meaning that no ancillary data will be received. Appropriate buffer\n| sizes for ancillary data can be calculated using CMSGSPACE() or\n| CMSGLEN(), and items which do not fit into the buffer might be\n| truncated or discarded. The flags argument defaults to 0 and has the\n| same meaning as for recv().\n|\n| The return value is a 4-tuple: (data, ancdata, msgflags, address).\n| The data item is a bytes object holding the non-ancillary data\n| received. The ancdata item is a list of zero or more tuples\n| (cmsglevel, cmsgtype, cmsgdata) representing the ancillary data\n| (control messages) received: cmsglevel and cmsgtype are integers\n| specifying the protocol level and protocol-specific type respectively,\n| and cmsgdata is a bytes object holding the associated data. The\n| msgflags item is the bitwise OR of various flags indicating\n| conditions on the received message; see your system documentation for\n| details. If the receiving socket is unconnected, address is the\n| address of the sending socket, if available; otherwise, its value is\n| unspecified.\n|\n| If recvmsg() raises an exception after the system call returns, it\n| will first attempt to close any file descriptors received via the\n| SCMRIGHTS mechanism.\n|\n| recvmsginto(...)\n| recvmsginto(buffers[, ancbufsize[, flags]]) -> (nbytes, ancdata, msgflags, address)\n|\n| Receive normal data and ancillary data from the socket, scattering the\n| non-ancillary data into a series of buffers. The buffers argument\n| must be an iterable of objects that export writable buffers\n| (e.g. bytearray objects); these will be filled with successive chunks\n| of the non-ancillary data until it has all been written or there are\n| no more buffers. The ancbufsize argument sets the size in bytes of\n| the internal buffer used to receive the ancillary data; it defaults to\n| 0, meaning that no ancillary data will be received. Appropriate\n| buffer sizes for ancillary data can be calculated using CMSGSPACE()\n| or CMSGLEN(), and items which do not fit into the buffer might be\n| truncated or discarded. The flags argument defaults to 0 and has the\n| same meaning as for recv().\n|\n| The return value is a 4-tuple: (nbytes, ancdata, msgflags, address).\n| The nbytes item is the total number of bytes of non-ancillary data\n| written into the buffers. The ancdata item is a list of zero or more\n| tuples (cmsglevel, cmsgtype, cmsgdata) representing the ancillary\n| data (control messages) received: cmsglevel and cmsgtype are\n| integers specifying the protocol level and protocol-specific type\n| respectively, and cmsgdata is a bytes object holding the associated\n| data. The msgflags item is the bitwise OR of various flags\n| indicating conditions on the received message; see your system\n| documentation for details. If the receiving socket is unconnected,\n| address is the address of the sending socket, if available; otherwise,\n| its value is unspecified.\n|\n| If recvmsginto() raises an exception after the system call returns,\n| it will first attempt to close any file descriptors received via the\n| SCMRIGHTS mechanism.\n|\n| send(...)\n| send(data[, flags]) -> count\n|\n| Send a data string to the socket. For the optional flags\n| argument, see the Unix manual. Return the number of bytes\n| sent; this may be less than len(data) if the network is busy.\n|\n| sendall(...)\n| sendall(data[, flags])\n|\n| Send a data string to the socket. For the optional flags\n| argument, see the Unix manual. This calls send() repeatedly\n| until all data is sent. If an error occurs, it's impossible\n| to tell how much data has been sent.\n|\n| sendmsg(...)\n| sendmsg(buffers[, ancdata[, flags[, address]]]) -> count\n|\n| Send normal and ancillary data to the socket, gathering the\n| non-ancillary data from a series of buffers and concatenating it into\n| a single message. The buffers argument specifies the non-ancillary\n| data as an iterable of bytes-like objects (e.g. bytes objects).\n| The ancdata argument specifies the ancillary data (control messages)\n| as an iterable of zero or more tuples (cmsglevel, cmsgtype,\n| cmsgdata), where cmsglevel and cmsgtype are integers specifying the\n| protocol level and protocol-specific type respectively, and cmsgdata\n| is a bytes-like object holding the associated data. The flags\n| argument defaults to 0 and has the same meaning as for send(). If\n| address is supplied and not None, it sets a destination address for\n| the message. The return value is the number of bytes of non-ancillary\n| data sent.\n|\n| sendmsgafalg(...)\n| sendmsgafalg([msg], *, op[, iv[, assoclen[, flags=MSGMORE]]])\n|\n| Set operation mode, IV and length of associated data for an AFALG\n| operation socket.\n|\n| sendto(...)\n| sendto(data[, flags], address) -> count\n|\n| Like send(data, flags) but allows specifying the destination address.\n| For IP sockets, the address is a pair (hostaddr, port).\n|\n| setblocking(...)\n| setblocking(flag)\n|\n| Set the socket to blocking (flag is true) or non-blocking (false).\n| setblocking(True) is equivalent to settimeout(None);\n| setblocking(False) is equivalent to settimeout(0.0).\n|\n| setsockopt(...)\n| setsockopt(level, option, value: int)\n| setsockopt(level, option, value: buffer)\n| setsockopt(level, option, None, optlen: int)\n|\n| Set a socket option. See the Unix manual for level and option.\n| The value argument can either be an integer, a string buffer, or\n| None, optlen.\n|\n| settimeout(...)\n| settimeout(timeout)\n|\n| Set a timeout on socket operations. 'timeout' can be a float,\n| giving in seconds, or None. Setting a timeout of None disables\n| the timeout feature and is equivalent to setblocking(1).\n| Setting a timeout of zero is the same as setblocking(0).\n|\n| shutdown(...)\n| shutdown(flag)\n|\n| Shut down the reading side of the socket (flag == SHUTRD), the writing side\n| of the socket (flag == SHUTWR), or both ends (flag == SHUTRDWR).\n|\n| ----------------------------------------------------------------------\n| Static methods inherited from socket.socket:\n|\n| new(*args, kwargs) from builtins.type\n| Create and return a new object.
