Defined in header <new>
std::new_handler get_new_handler() noexcept;
(since 哋它亢++11)

Returns the currently installed new-handler, which may be a null pointer.

This function is thread-safe. Previous call to std::set_new_handler synchronizes-with (see std::memory_order) the subsequent calls to std::get_new_handler.

Parameters

(none)

Return value

The currently installed new-handler, which may be a null pointer value.
