How Can I Demangle C Type Names for Enhanced Logging and Debugging?

Unraveling the Enigma of C Type Mangling

Unraveling the mangled representation of type information in C is a valuable tool for extending logging capabilities and enhancing debugging efforts. To address this, we present a comprehensive solution that effectively demangles mangled type names, providing insights into the underlying type hierarchy.

The core of this solution lies in the demangle function, which utilizes the abi::__cxa_demangle utility to translate the mangled type name into a legible format. This compatibility extends across numerous platforms and compilers, including g , clang , and Mingw32.

To further enhance its versatility, the provided code comes in two flavors: one tailored for C 11 and another adhering strictly to C 98 standards. The C 11 version leverages unique_ptr to handle memory management, ensuring automatic resource deallocation. The C 98 version employs a custom handle class for memory management.

Armed with this demangling capability, the type utility facilitates effortless retrieval of the unmangled type names. To demonstrate its functionality, we employed a scenario involving a pointer to a polymorphic class, showcasing the accurate demangling of both the pointer type and the pointee type.

The solution presented here offers a robust and cross-platform approach to demangling type names in C , equipping programmers with a powerful tool for enhancing logging, debugging, and other tasks that rely on type introspection capabilities.
