socket.recvmsg_into(buffers[, ancbufsize[, flags]]) Receive normal data and ancillary data from the socket, behaving as recvmsg() would, but scatter the non-ancillary data into a series of buffers instead of returning a new bytes object. 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 operating system

socket.recvmsg(bufsize[, ancbufsize[, flags]]) 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 default

socket.recv(bufsize[, flags]) Receive data from the socket. The return value is a bytes object representing the data received. The maximum amount of data to be received at once is specified by bufsize. See the Unix manual page recv(2) for the meaning of the optional argument flags; it defaults to zero. Note For best match with hardware and network realities, the value of bufsize should be a relatively small power of 2, for example, 4096. Changed in version 3.5: If the system call is inter

socket.recvfrom_into(buffer[, nbytes[, flags]]) Receive data from the socket, writing it into buffer instead of creating a new bytestring. The return value is a pair (nbytes, address) where nbytes is the number of bytes received and address is the address of the socket sending the data. See the Unix manual page recv(2) for the meaning of the optional argument flags; it defaults to zero. (The format of address depends on the address family — see above.)

socket.recvfrom(bufsize[, flags]) Receive data from the socket. The return value is a pair (bytes, address) where bytes is a bytes object representing the data received and address is the address of the socket sending the data. See the Unix manual page recv(2) for the meaning of the optional argument flags; it defaults to zero. (The format of address depends on the address family — see above.) Changed in version 3.5: If the system call is interrupted and the signal handler does not raise an

socket.proto The socket protocol.

socket.get_inheritable() Get the inheritable flag of the socket’s file descriptor or socket’s handle: True if the socket can be inherited in child processes, False if it cannot. New in version 3.4.

socket.ioctl(control, option) Platform: Windows The ioctl() method is a limited interface to the WSAIoctl system interface. Please refer to the Win32 documentation for more information. On other platforms, the generic fcntl.fcntl() and fcntl.ioctl() functions may be used; they accept a socket object as their first argument.

socket.gettimeout() Return the timeout in seconds (float) associated with socket operations, or None if no timeout is set. This reflects the last call to setblocking() or settimeout().

socket.makefile(mode='r', buffering=None, *, encoding=None, errors=None, newline=None) Return a file object associated with the socket. The exact returned type depends on the arguments given to makefile(). These arguments are interpreted the same way as by the built-in open() function, except the only supported mode values are 'r' (default), 'w' and 'b'. The socket must be in blocking mode; it can have a timeout, but the file object’s internal buffer may end up in an inconsistent state if a
