⚙️ FUNCTIONS

• cancel_dump_traceback_later() — cancel the previous call to dump_traceback_later().
• disable() — disable the fault handler
• dump_traceback(file=sys.stderr, all_threads=True) — dump the traceback of the current thread, or of all threads if all_threads is True, into file
• dump_traceback_later(timeout, repeat=False, file=sys.stderr, exit=False) — dump the traceback of all threads in timeout seconds, or each timeout seconds if repeat is True. If exit is True, call _exit(1) which is not safe.
• enable(file=sys.stderr, all_threads=True) — enable the fault handler
• is_enabled() → bool — check if the handler is enabled
• register(signum, file=sys.stderr, all_threads=True, chain=False) — register a handler for the signal 'signum': dump the traceback of the current thread, or of all threads if all_threads is True, into file
• unregister(signum) — unregister the handler of the signal 'signum' registered by register()
