Hi Michele,

My question is: it is possible to call the function from/to a specific thread?

you could use deferToThread() to run a task in a separate thread and get the results in the main thread. here are the docs: http://twistedmatrix.com/documents/current/api/twisted.internet.threads.html... here is a small example which asks for user input in a separate thread: -------- from twisted.internet import reactor, defer, threads def input(): return threads.deferToThread(blocking_task) def blocking_task(): print "working... enter something to end task" return raw_input() def got_result(data): print "the long-running task results in:", data reactor.stop() input().addCallback(got_result) reactor.run() -------- is this what you want to do?

Hi all, I have a project where I writing the "server" (on win xp) and I want to communicate with a client, so twisted it's all I need. Into the "server" I have also a python bind to a dll (with ctypes) and I see strange problems (windows crashes) when I call a dll function inside a thread. My thread it's a twisted "Protocol". My question is: it is possible to call the function from/to a specific thread? So somethink like:

class MyDll: def funct(self, callBack): #do the work reactor.call_in_main_thrad(callBack)

tid = create_a_thread_and_load_MyDll() # where I make the dll instance and all the work need into a thread

#into a someone function into the main thread

def callBack(): # a simple callback

reactor.callIntoThread(tid, funct, callBack)

Is this possible with twisted? (Does I'm dreaming?)

P.s. If I try with the wx "reactor" (so wx.MainLoop), I see no problem! In that case, I instance the dll into the class __init__ (inherit from wx.Frame) and into a someone event (i.e. Button click) I call a dll funct and all work without crash...

Thanks, Michele
