msgid ""
"The following top-level asyncio functions can be used to create and work "

msgid ""
"Establish a network connection and return a pair of ``(reader, writer)`` "
"objects."
msgstr ""

msgid ""
"The returned *reader* and *writer* objects are instances of :class:"
"`StreamReader` and :class:`StreamWriter` classes."
msgstr ""

msgid ""
"*limit* determines the buffer size limit used by the returned :class:"
"`StreamReader` instance.  By default the *limit* is set to 64 KiB."
msgstr ""

msgid ""
"The rest of the arguments are passed directly to :meth:`loop."
"create_connection`."
msgstr ""

msgid ""
"The *sock* argument transfers ownership of the socket to the :class:"
"`StreamWriter` created. To close the socket, call its :meth:`~asyncio."
"StreamWriter.close` method."
msgstr ""

msgid "Added the *ssl_handshake_timeout* parameter."
msgstr ""

msgid "Added the *happy_eyeballs_delay* and *interleave* parameters."
msgstr ""

msgid "Removed the *loop* parameter."
msgstr ""

msgid "Added the *ssl_shutdown_timeout* parameter."
msgstr ""

msgid "Start a socket server."
msgstr ""

msgid ""
"The *client_connected_cb* callback is called whenever a new client "

msgstr ""

msgid ""
"*client_connected_cb* can be a plain callable or a :ref:`coroutine function "

msgid ""
"The method attempts to write the *data* to the underlying socket "
"immediately. If that fails, the data is queued in an internal write buffer "

msgid "The method should be used along with the ``drain()`` method::"

"Return ``True`` if the underlying transport supports the :meth:`write_eof` "

msgstr ""

msgid ""
"writer.write(data)\n"

msgstr ""

msgid ""
"This is a flow control method that interacts with the underlying IO write "

"*server_hostname*: sets or overrides the host name that the target server's "

"*ssl_handshake_timeout* is the time in seconds to wait for the TLS handshake "

msgid "Wait until the stream is closed."
