:mod:`os` --- basic "operating system" services
|
||
|
|
===============================================
|
||
|
|
|
||
|
|
.. module:: os
|
||
|
|
:synopsis: basic "operating system" services
|
||
|
|
|
||
|
|
The ``os`` module contains functions for filesystem access and ``urandom``.
|
||
|
|
|
||
|
|
The filesystem has ``/`` as the root directory, and the available physical
|
||
|
|
drives are accessible from here. They are currently:
|
||
|
|
|
||
|
|
/flash -- the internal flash filesystem
|
||
|
|
/sd -- the SD card (if it exists)
|
||
|
|
|
||
|
|
On boot up, the current directory is ``/flash`` if no SD card is inserted,
|
||
|
|
otherwise it is ``/sd``.
|
||
