Lua coroutine standard library
Version: alpha
Functions
coroutine.create()
coroutine.create(f)
Creates a new coroutine, with body f.
f must be a Lua function.
Returns this new coroutine,
an object with type
"thread".
PARAMETERS
coroutine.resume()
coroutine.resume(co,[val1],[...])
Starts or continues the execution of coroutine co.
The first time you resume a coroutine,
it starts running its body.
The values val1, ... are passed
as the arguments to the body function.
If the coroutine has yielded,
resume restarts it;
the values val1, ... are passed
as the results from the yield.
If the coroutine runs without any errors,
resume returns
true plus any values passed to yield
(if the coroutine yields) or any values returned by the body function
(if the coroutine terminates).
If there is any error,
resume returns
false plus the error message.
PARAMETERS
coroutine.running()
coroutine.running()
Returns the running coroutine,
or
nil when called by the main thread.
PARAMETERS
coroutine.status()
coroutine.status(co)
Returns the status of coroutine co, as a string:
"running",
if the coroutine is running (that is, it called status);
"suspended", if the coroutine is suspended in a call to yield,
or if it has not started running yet;
"normal" if the coroutine is active but not running
(that is, it has resumed another coroutine);
and
"dead" if the coroutine has finished its body function,
or if it has stopped with an error.
PARAMETERS
coroutine.wrap()
coroutine.wrap(f)
Creates a new coroutine, with body f.
f must be a Lua function.
Returns a function that resumes the coroutine each time it is called.
Any arguments passed to the function behave as the
extra arguments to resume.
Returns the same values returned by resume,
except the first boolean.
In case of error, propagates the error.
PARAMETERS
coroutine.yield()
coroutine.yield(...)
Suspends the execution of the calling coroutine.
The coroutine cannot be running a C function,
a metamethod, or an iterator.
Any arguments to yield are passed as extra results to resume.
