twisted.internet.interfaces.IReactorThreads : API documentation

Method	callInThread	Run the callable object in a separate thread.
Method	callFromThread	Cause a function to be executed by the reactor thread.
Method	suggestThreadPoolSize	Suggest the size of the internal threadpool used to dispatch functions passed to `callInThread`.

def callInThread(callable, *args, **kwargs): (source)

Run the callable object in a separate thread.

def callFromThread(callable, *args, **kw): (source)

Cause a function to be executed by the reactor thread.

Use this method when you want to run a function in the reactor's thread from another thread. Calling callFromThread should wake up the main thread (where reactor.run() is executing) and run the given callable in that thread.

If you're writing a multi-threaded application the callable may need to be thread safe, but this method doesn't require it as such. If you want to call a function in the next mainloop iteration, but you're in the same thread, use callLater with a delay of 0.

def suggestThreadPoolSize(size): (source)

Suggest the size of the internal threadpool used to dispatch functions passed to callInThread.
