Hello,
I have a Python module written in C that spawns and kills processes
using OS-specific mechanisms. I want to kill all spawned processes when
the interpreter exits. I tried to wrap every spawned process in a
Python object like this:
import cmodule
class Process:
__init__(self, execname): self.pid = cmodule.spawn(execname)
__del__(self): cmodule.kill(self.pid)
p = Process("foo")
but this does not work, I am getting and exception inidicating that
'cmodule' is 'None' in '__del__()'.
Moreover, the Language Reference states that "It is not guaranteed that
__del__() methods are called for objects that still exist when the
interpreter exits", so it looks like this approach is wrong anyway. How
do I do this right?
Thanks very much in advance
Grzegorz
PS: Python 2.3.3
