ctypes.pythonapi.PyThreadState_SetAsyncExc 的解析 基本用途: ctypes.pythonapi.PyThreadState_SetAsyncExc 是一个底层的 C 函数,它允许你向一个指定的线程异步地发送一个异常。这意味着你可以强制一个线程在执行过程中抛出一个异常,从而可能提前终止该线程的执行。 函数签名和参数: ...
使用PyThreadState_SetAsyncExc方法可以在大部分情况下满足我们直接退出线程的需求，但它仅仅是计划线程的退出执行，并不会立即杀死线程。特别是在线程正在执行外部C库时，这种方法可能无法立即生效。这个方法需注意处理，以避免信号处理问题。尝试使用sleep(100)方法来杀死一个线程，你会发现它实际上会在100秒后被“杀死...

Python中可通过调用threading.Thread直接创建线程,如下所示,调用threading.Thread通常需要传入两个参数:target为“线程函数”;args为传递给“线程函数”的参数,必须为tuple类型。 import threading def worker(name): print("thread %s is running" % name)
