在python中实现强制关闭线程的示例
如下所示：
importthreading
importtime
importinspect
importctypes
def_async_raise(tid,exctype):
"""raisestheexception,performscleanupifneeded"""
tid=ctypes.c_long(tid)
ifnotinspect.isclass(exctype):
exctype=type(exctype)
res=ctypes.pythonapi.PyThreadState_SetAsyncExc(tid,ctypes.py_object(exctype))
ifres==0:
raiseValueError("invalidthreadid")
elifres!=1:
#"""ifitreturnsanumbergreaterthanone,you'reintrouble,
#andyoushouldcallitagainwithexc=NULLtoreverttheeffect"""
ctypes.pythonapi.PyThreadState_SetAsyncExc(tid,None)
raiseSystemError("PyThreadState_SetAsyncExcfailed")
defstop_thread(thread):
_async_raise(thread.ident,SystemExit)
classTestThread(threading.Thread):
defrun(self):
print
"begin"
whileTrue:
time.sleep(0.1)
print('end')
if__name__=="__main__":
t=TestThread()
t.start()
time.sleep(1)
stop_thread(t)
print('stoped')
