.. function:: addaudithook(hook)

Append the callable *hook* to the list of active auditing hooks for the

current interpreter.

current (sub)interpreter.

When an auditing event is raised through the :func:`sys.audit` function, each

hook will be called in the order it was added with the event name and the

tuple of arguments. Native hooks added by :c:func:`PySys_AddAuditHook` are

called first, followed by hooks added in the current interpreter. Hooks

called first, followed by hooks added in the current (sub)interpreter. Hooks

can then log the event, raise an exception to abort the operation,

or terminate the process entirely.

Ensures interpreter-level audit hooks receive the

``cpython.PyInterpreterState_New`` event when called through the

``_xxsubinterpreters`` module.
