signal.getsignal()
signal.getsignal() is a Python function in the Signal Module category. Returns the current signal handler for a given signal. The syntax is signal.getsignal(signalnum). Returns: Current handler or SIG_DFL/SIG_IGN. A typical example: old_handler = signal.getsignal(signal.SIGINT)
print(old_handler) # signal.default_int_handler. A close sibling is signal.signal(), which sets a handler for a signal (like SIGINT, SIGTERM). A close sibling is signal.pause(), which blocks until a signal is received (Unix only). A close sibling is signal.alarm(), which sets a SIGALRM timer in seconds. Only one alarm can be pending. A close sibling is signal.setitimer(), which sets an interval timer with microsecond precision. More about this category: Async event handling — signal, alarm, pause, setitimer.
