The clipboard from the host OS. Might be unavailable on some platforms.

----

.. _class_OS_property_current_screen:

- :ref:`int<class_int>` **current_screen**

+-----------+---------------------------+
| *Default* | ``0``                     |
+-----------+---------------------------+
| *Setter*  | set_current_screen(value) |
+-----------+---------------------------+
| *Getter*  | get_current_screen()      |

----

.. _class_OS_property_exit_code:

- :ref:`int<class_int>` **exit_code**

+-----------+----------------------+
| *Default* | ``0``                |
+-----------+----------------------+
| *Setter*  | set_exit_code(value) |
+-----------+----------------------+
| *Getter*  | get_exit_code()      |
+-----------+----------------------+

The exit code passed to the OS when the main loop exits. By convention, an exit code of ``0`` indicates success whereas a non-zero exit code indicates an error. For portability reasons, the exit code should be set between 0 and 125 (inclusive).

**Note:** This value will be ignored if using :ref:`SceneTree.quit<class_SceneTree_method_quit>` with an ``exit_code`` argument passed.

----

.. _class_OS_property_keep_screen_on:

- :ref:`bool<class_bool>` **keep_screen_on**

+-----------+---------------------------+
| *Default* | ``true``                  |
+-----------+---------------------------+
| *Setter*  | set_keep_screen_on(value) |
+-----------+---------------------------+
| *Getter*  | is_keep_screen_on()       |
+-----------+---------------------------+

If ``true``, the engine tries to keep the screen on while the game is running. Useful on mobile.

----

.. _class_OS_property_low_processor_usage_mode:

- :ref:`bool<class_bool>` **low_processor_usage_mode**

+-----------+-------------------------------------+
| *Default* | ``false``                           |
+-----------+-------------------------------------+
| *Setter*  | set_low_processor_usage_mode(value) |
+-----------+-------------------------------------+
| *Getter*  | is_in_low_processor_usage_mode()    |
+-----------+-------------------------------------+

If ``true``, the engine optimizes for low processor usage by only refreshing the screen if needed. Can improve battery consumption on mobile.

----

.. _class_OS_property_low_processor_usage_mode_sleep_usec:

- :ref:`int<class_int>` **low_processor_usage_mode_sleep_usec**

+-----------+------------------------------------------------+

+-----------+------------------------------------------------+
| *Setter*  | set_low_processor_usage_mode_sleep_usec(value) |
+-----------+------------------------------------------------+
| *Getter*  | get_low_processor_usage_mode_sleep_usec()      |
+-----------+------------------------------------------------+

The amount of sleeping between frames when the low-processor usage mode is enabled (in microseconds). Higher values will result in lower CPU usage.

----

.. _class_OS_property_max_window_size:

- :ref:`Vector2<class_Vector2>` **max_window_size**

+-----------+----------------------------+
| *Default* | ``Vector2( 0, 0 )``        |

| *Getter*  | get_max_window_size()      |
+-----------+----------------------------+

The maximum size of the window (without counting window manager decorations). Does not affect fullscreen mode. Set to ``(0, 0)`` to reset to the system default value.

----

.. _class_OS_property_min_window_size:

- :ref:`Vector2<class_Vector2>` **min_window_size**

+-----------+----------------------------+
| *Default* | ``Vector2( 0, 0 )``        |
+-----------+----------------------------+
| *Setter*  | set_min_window_size(value) |
+-----------+----------------------------+
| *Getter*  | get_min_window_size()      |
+-----------+----------------------------+

The minimum size of the window (without counting window manager decorations). Does not affect fullscreen mode. Set to ``(0, 0)`` to reset to the system default value.

----

.. _class_OS_property_screen_orientation:

- :ref:`ScreenOrientation<enum_OS_ScreenOrientation>` **screen_orientation**

+-----------+-------------------------------+
| *Default* | ``0``                         |

+-----------+-----------------------------------+
| *Setter*  | set_vsync_via_compositor(value)   |
+-----------+-----------------------------------+
| *Getter*  | is_vsync_via_compositor_enabled() |

Method Descriptions

- void **alert** **(** :ref:`String<class_String>` text, :ref:`String<class_String>` title="Alert!" **)**

Displays a modal dialog box using the host OS' facilities. Execution is blocked until the dialog is closed.

----

.. _class_OS_method_can_draw:

- :ref:`bool<class_bool>` **can_draw** **(** **)** const

Returns ``true`` if the host OS allows drawing.

----

.. _class_OS_method_can_use_threads:

- :ref:`bool<class_bool>` **can_use_threads** **(** **)** const

Returns ``true`` if the current host platform is using multiple threads.

----

.. _class_OS_method_center_window:

- void **center_window** **(** **)**

----

.. _class_OS_method_close_midi_inputs:

----

.. _class_OS_method_delay_msec:

- void **delay_msec** **(** :ref:`int<class_int>` msec **)** const

Delay execution of the current thread by ``msec`` milliseconds.

----

.. _class_OS_method_delay_usec:

- void **delay_usec** **(** :ref:`int<class_int>` usec **)** const

Delay execution of the current thread by ``usec`` microseconds.

----

.. _class_OS_method_dump_memory_to_file:

- void **dump_memory_to_file** **(** :ref:`String<class_String>` file **)**

Dumps the memory allocation ringlist to a file (only works in debug).

Entry format per line: "Address - Size - Description".

----

.. _class_OS_method_dump_resources_to_file:

- void **dump_resources_to_file** **(** :ref:`String<class_String>` file **)**

Dumps all used resources to file (only works in debug).

Entry format per line: "Resource Type : Resource Location".

At the end of the file is a statistic of all used Resource Types.

----

.. _class_OS_method_execute:

- :ref:`int<class_int>` **execute** **(** :ref:`String<class_String>` path, :ref:`PackedStringArray<class_PackedStringArray>` arguments, :ref:`bool<class_bool>` blocking=true, :ref:`Array<class_Array>` output=[  ], :ref:`bool<class_bool>` read_stderr=false **)**

Execute the file at the given path with the arguments passed as an array of strings. Platform path resolution will take place. The resolved file must exist and be executable.

The arguments are used in the given order and separated by a space, so ``OS.execute("ping", ["-w", "3", "godotengine.org"], false)`` will resolve to ``ping -w 3 godotengine.org`` in the system's shell.

This method has slightly different behavior based on whether the ``blocking`` mode is enabled.

If ``blocking`` is ``true``, the Godot thread will pause its execution while waiting for the process to terminate. The shell output of the process will be written to the ``output`` array as a single string. When the process terminates, the Godot thread will resume execution.

If ``blocking`` is ``false``, the Godot thread will continue while the new process runs. It is not possible to retrieve the shell output in non-blocking mode, so ``output`` will be empty.

The return value also depends on the blocking mode. When blocking, the method will return an exit code of the process. When non-blocking, the method returns a process ID, which you can use to monitor the process (and potentially terminate it with :ref:`kill<class_OS_method_kill>`). If the process forking (non-blocking) or opening (blocking) fails, the method will return ``-1`` or another exit code.

Example of blocking mode and retrieving the shell output:

::

    var output = []
    var exit_code = OS.execute("ls", ["-l", "/tmp"], true, output)

Example of non-blocking mode, running another instance of the project and storing its process ID:

::

    var pid = OS.execute(OS.get_executable_path(), [], false)

If you wish to access a shell built-in or perform a composite command, a platform-specific shell can be invoked. For example:

::

    OS.execute("CMD.exe", ["/C", "cd %TEMP% && dir"], true, output)

**Note:** This method is implemented on Android, iOS, Linux, macOS and Windows.
