Is there a reference that decodes the output from typeid().name()?
The C++ Standard does not specify the value of that expression.
It could very well be the null string in a conforming specification.
Which is the reason I posted to gnu.g++.help not c++.
Good point.
GCC implements the Itanium C++ ABI, specified here:
http://www.codesourcery.com/public/cxx-abi/abi.html
You will see that, contrary to my expectation, this specification does
in fact guarantee some form to that expression.
Search for the demangler API.
Thanks.
