TCPServer
=========

**Inherits:** :ref:`SocketServer<class_SocketServer>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

A TCP server.

.. rst-class:: classref-introduction-group

Description
-----------

A TCP server. Listens to connections on a port and returns a :ref:`StreamPeerTCP<class_StreamPeerTCP>` when it gets an incoming connection.

\ **Note:** When exporting to Android, make sure to enable the ``INTERNET`` permission in the Android export preset before exporting the project or using one-click deploy. Otherwise, network communication of any kind will be blocked by Android.

Method Descriptions
-------------------

.. _class_TCPServer_method_get_local_port:

.. rst-class:: classref-method

:ref:`int<class_int>` **get_local_port**\ (\ ) |const| :ref:`🔗<class_TCPServer_method_get_local_port>`

Returns the local port this server is listening to.

.. rst-class:: classref-item-separator

----

.. _class_TCPServer_method_listen:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **listen**\ (\ port\: :ref:`int<class_int>`, bind_address\: :ref:`String<class_String>` = "*"\ ) :ref:`🔗<class_TCPServer_method_listen>`

Listen on the ``port`` binding to ``bind_address``.

If ``bind_address`` is set as ``"*"`` (default), the server will listen on all available addresses (both IPv4 and IPv6).

If ``bind_address`` is set as ``"0.0.0.0"`` (for IPv4) or ``"::"`` (for IPv6), the server will listen on all available addresses matching that IP type.

If ``bind_address`` is set to any valid address (e.g. ``"192.168.1.101"``, ``"::1"``, etc.), the server will only listen on the interface with that address (or fail if no interface with the given address exists).

.. _class_TCPServer_method_take_connection:

.. rst-class:: classref-method

:ref:`StreamPeerTCP<class_StreamPeerTCP>` **take_connection**\ (\ ) :ref:`🔗<class_TCPServer_method_take_connection>`

If a connection is available, returns a StreamPeerTCP with the connection.
