Function make_socket

dns/query.py:324–354

Make a socket. This function uses the module's ``socket_factory`` to make a socket of the specified address family and type. *af*, a ``socket.AddressFamily`` or ``int`` is the address family, either ``socket.AF_INET`` or ``socket.AF_INET6``. *type*, a ``socket.SocketKind`` is

(
    af: socket.AddressFamily | int,
    type: socket.SocketKind,
    source: Any | None = None,
)

    af: socket.AddressFamily | int,

    *af*, a ``socket.AddressFamily`` or ``int`` is the address family, either
    ``socket.AF_INET`` or ``socket.AF_INET6``.

    *type*, a ``socket.SocketKind`` is the type of socket, e.g. ``socket.SOCK_DGRAM``,
    a datagram socket, or ``socket.SOCK_STREAM``, a stream socket.  Note that the
    ``proto`` attribute of a socket is always zero with this API, so a datagram socket
    will always be a UDP socket, and a stream socket will always be a TCP socket.

    *source* is the source address and port to bind to, if any.  The default is
    ``None`` which will bind to the wildcard address and a randomly chosen port.
    If not ``None``, it should be a (low-level) address tuple appropriate for *af*.
