[edit] Explanation
The keyword nullptr
denotes the null pointer literal. It is an unspecified prvalue of type std::nullptr_t. There exist implicit conversions from nullptr
to null pointer value of any pointer type and any pointer to member type. Similar conversions exist for any value of type std::nullptr_t as well as for the macro NULL, the null pointer constant.
[edit] Example
Demonstrates how nullptr allows forwarding via a template function.
