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

Operating System functions. OS Wraps the most common functionality to communicate with the host Operating System, such as: mouse grabbing, mouse cursors, clipboard, video mode, date and time, timers, environment variables, execution of binaries, command line, etc.

Member Function Description
---------------------------

.. _class_OS_alert:

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

Displays a modal dialog box utilizing the host OS.

.. _class_OS_can_draw:

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

Return true if the host OS allows drawing.

.. _class_OS_can_use_threads:

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

Returns if the current host platform is using multiple threads.

.. _class_OS_delay_msec:

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

Delay executing of the current thread by given milliseconds.

.. _class_OS_delay_usec:

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

Delay executing of the current thread by given microseconds.

.. _class_OS_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_dump_resources_to_file:

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