reuse_portc C s
t d S)a A coroutine which creates a TCP server bound to host and port.
The return value is a Server object which can be used to stop
the service.
If host is an empty string or None all interfaces are assumed
and a list of multiple sockets will be returned (most likely
one for IPv4 and another one for IPv6). The host parameter can also be a
sequence (e.g. list) of hosts to bind to.
family can be set to either AF_INET or AF_INET6 to force the
socket to use IPv4 or IPv6. If not set it will be determined
from host (defaults to AF_UNSPEC).
flags is a bitmask for getaddrinfo().
sock can optionally be specified in order to use a preexisting
socket object.
backlog is the maximum number of queued connections passed to
listen() (defaults to 100).
ssl can be set to an SSLContext to enable SSL over the
accepted connections.
reuse_address tells the kernel to reuse a local socket in
TIME_WAIT state, without waiting for its natural timeout to
expire. If not specified will automatically be set to True on
UNIX.
reuse_port tells the kernel to allow this endpoint to be bound to
the same port as other existing endpoints are bound to, so long as
they all set this flag when being created. This option is not
supported on Windows.

supported on Windows and some UNIX's. If the

BaseDefaultEventLoopPolicya Default policy implementation for accessing the event loop.
In this policy, each thread has its own event loop. However, we
only automatically create an event loop by default for the main
thread; other threads by default have no event loop.
Other policies may have different rules (e.g. a single global
event loop, or automatically creating an event loop per thread, or
using some other notion of context to which an event loop is
associated).
