signal.setitimer()
signal.setitimer() is a Python function in the Signal Module category. Sets an interval timer with microsecond precision. The syntax is signal.setitimer(which, seconds, interval=0.0). A typical example: signal.setitimer(signal.ITIMER_REAL, 1.0, 0.5)
# Signal every 0.5s after 1s initial delay. 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.getsignal(), which returns the current signal handler for a given signal. More about this category: Async event handling — signal, alarm, pause, setitimer.
