C++ Function Argument

Hello

Today I was browsing the gtkmm documentation about glib::ustring type and say one method's arguments:

Code:

ustring (const ustring& other)

What shoud usting& mean? It's not a ustring type, it's neither a ustring reference(const ustring & other - i think this is reference) and nor ustring pointer(const ustring* other).

Thanks in advance

Cheers,

Umm, const ustring& is a reference.
