Can I ungarble GCC's RTTI names?

Using gcc, when I ask for an object/variable's type using typeid, I get a different result from the type_info::name method from what I'd expect to get on Windows. I Googled around a bit, and found out that RTTI names are implementation-specific.

Problem is, I want to get a type's name as it wo开发者_StackOverflow社区uld be returned on Windows. Is there an easy way to do this?

If it's what you're asking, there is no compiler switch that would make gcc behave like msvc regarding the name returned by type_info::name().

However, in your code you can rely on the gcc specific __cxa_demangle function.

There is in fact an answer on SO that addresses your problem.

Reference: libstdc++ manual, Chapter 40. Demangling.

c++ function names really include all the return and argument type information as well as the class and method name. When compiled, they are 'mangled' into a standard form (standard for each compiler) that can act as an assembler symbol and includes all the type information.

You need to run a function or program to reverse this mangling, called a demangler.

try running

c++filt myoutput.txt

on the output of the function. This demangles the real symbol name back into a human readable form.

Based on this other question Is there an online name demangler for C++? I've written a online tool for this: c++filtjs
