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

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

This function is thread-safe. Previous call tostd::set_new_handlersynchronizes-with (seestd::memory_order) the subsequent calls tostd::get_new_handler.

[edit]Parameters

(none)

[edit]Return value

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