A problem about coroutine's status

["lee" <leeyacn@...>]

Hi,

We know that Lua’s coroutine has four statuses – suspended, running, dead, normal.

The “coroutine.status()” is used to check a coroutine’s current status.

The below example can tell me in which status the corountine exist.

 

function foo()

   print("foo", 1)

   coroutine.yield()

   print("foo", 2)

  

end

 

co = coroutine.create(foo) -- create a coroutine with foo as the entry

 

=type(co)

  

function foo()

   print("foo", 1)

   coroutine.yield()

   print("foo", 2)

  

end

 

co = coroutine.create(foo) -- create a coroutine with foo as the entry

 

print(type(co))

print(coroutine.status(co)) -- suspended

coroutine.resume(co)

print(coroutine.status(co)) -- suspended

coroutine.resume(co)

print(coroutine.status(co)) -- dead

 

who can give me a example that show “running” and “normal” status ?

That’s, which conditions we can receive coroutine’s running and normal status?

 

Thanks.
