How can I get methods to work as callbacks with python ctypes?

Question

I have an C api that i\'m interfacing with the python ctypes package. Everything works well, except this little tidbit.

To register functions as callbacks to some n

Answer 1

You can't, so far as I know, call a bound method because it is missing the self parameter. I solve this problem using a closure, like this:

CALLBACK = ctypes.CFUNCTYPE(None, ctypes.POINTER(Notification))

class MyClass(object):

    def getCallbackFunc(self):
        def func(Notification):
            self.doSomething(Notification)
        return CALLBACK(func)

    def doRegister(self):
        myLib.RegisterNofityCallback(45454, 0, self.getCallbackFunc())
