''You may be looking for alternative OS's for ComputerCraft. If so, go to the [[list of oses|list of OSes]].''

The Operating System API allows for interfacing with the Lua based Operating System itself.
{| border="1" cellpadding="2" cellspacing="0"
!style="background:#EEE" width="200px"|Method name
!style="background:#EEE" width="*"|Description
|-
|[[os.version()]]
|Returns the version of the OS the computer is running.
|-
|[[os.computerID()]]
|Returns the unique ID of this computer.
|-
|[[os.getComputerLabel()]]
|Returns the label of this computer.
|-
|[[os.setComputerLabel()]]
|Set the label of this computer.
|-
|[[os.run( environment, programpath, arguments )]]
|An advanced way of starting programs. A started program will have a given
Environment table which determines what functions it has available, as well as
any variables it will be able to access by default. You may prefer to use the
[[Shell (API)]] unless you need to do something special.
|-
|[[#api|os.loadAPI( name )]]
|Loads a lua script as an API, making it available to all programs.
|-
|[[#api|os.unloadAPI( name )]]
|Unloads a previously loaded API.
|-
|[[#pullEvent|os.pullEvent()]]
|Blocks until the computer has detected an event, then returns the event.
|-
|[[#pullEvent|os.pullEventRaw()]]
|Advanced version of pullEvent().
|-
|[[os.queueEvent()]]
|<no description given>
|-
|[[os.clock()]]
|Returns CPU time.
|-
|[[os.startTimer( timeout )]]
|Queues an event to be triggered after a number of seconds.
The ID of the timer is returned from this function to differentiate multiple
timers. Timers are one-shot, once they have fired an event you will need to
start another one if you need a recurring timer.
|-
|[[os.sleep( timeout )]]
|Makes the system wait a number of seconds before continuing in the program.
May also be used as simply "sleep( timeout )".
|-
|[[os.time()]]
|Returns the current Minecraft world time.
|-
|[[os.setAlarm( time )]]
|Queues an event to be triggered at the specific Minecraft world time.
|-
|[[os.shutdown()]]
|Turns off the computer.
|-
|[[os.reboot()]]
|Reboots the computer.

== <div id="api">API</div> ==

API are programs which are loaded in to the OS itself, and expose functions
which other programs may use. The stock [[Category:APIs|APIs that ship with
ComputerCraft]] are loaded in this way, and may be replaced by a computer's
user or programs.

== <div id="pullEvent">os.pullEvent()</div> ==

os.pullEvent() causes the current program to pause, retrieving the next event
from the computer's queue of events. If there is no event to read, then the
program will stall until such an event becomes available. Note that if a
program has not attempted to pull an event in the past ten seconds, it will
be forcefully terminated to prevent CPU waste in SMP environments.

pullEvent returns the name of the event that was read, as well as up to
five parameters:

<code>
local event, p1, p2, p3, p4, p5 = os.pullEvent()
</code>

os.pullEvent() is usually run inside a 'while true do' loop.

An advanced version of this method <code>os.pullEventRaw</code> bypasses the
normal handling of events from the OS. You may use this to act on the
"Terminate" event (triggered when holding Ctrl-T) for custom termination logic.

=== Event names ===

*[[Raw key events|"key": keypress]]
*"rednet_message": recieved a rednet message
*"terminate" (? please verify name): Ctrl-T held
