I believe it is a "reference to a pointer."

A reference for something means that it can be used anywhere the original can be used, AND any changes to the reference are reflected in the original. So for instance:

void func( int a, int& b )
{
a ++;
b ++;
}

int foo = 5, bar = 5;

func( foo, bar );

In this example, foo will remain unchanged because it was passed by value to the function, however, bar will reflect the increment because it was passed by reference.

Hello, It's similar to pointer to pointer (char**). Regards,
