You just have to pass the decorated name on the command line. The documentation has this example:

C:\>undname ?func1@a@@AAEXH@Z Microsoft (R) C++ Name Undecorator Copyright (C) Microsoft Corporation 1981-2000. All rights reserved.Undecoration of :- "?func1@a@@AAEXH@Z" is :- "private: void __thiscall a::func1(int)"
