Namemangled

Namemangled is a term used in computer programming, specifically within the context of compiled languages like C++ and others that support function overloading. It refers to the process where a compiler modifies the names of functions and variables to include additional information about their types and scope. This process is essential for the compiler to distinguish between functions or variables that have the same name but different parameters or are declared in different namespaces.

The exact mangling scheme varies between compilers and even between different versions of the same compiler. However, the general principle involves encoding the function's return type, parameter types, and namespace into its external name, which is what appears in the object code. This allows the linker to correctly resolve calls to functions, even when multiple functions share the same source code name. For example, a function named `print` that takes an integer and another function named `print` that takes a string would be given distinct, mangled names by the compiler.

Understanding name mangling is important for programmers who work with low-level programming, inter-language calls, or debugging. Without it, the linker would not be able to differentiate between identically named entities, leading to errors or incorrect program behavior. Tools like `nm` on Unix-like systems or Dependency Walker on Windows can display mangled names, and demangling utilities can translate them back into their original, human-readable forms, aiding in the debugging process.
