Editing Name mangling (section)

====Simple example====
A single C++ translation unit might define two functions named {{code|f()}}:

<syntaxhighlight lang="cpp">
int  f () { return 1; }
int  f (int)  { return 0; }
void g () { int i = f(), j = f(0); }
</syntaxhighlight>

These are distinct functions, with no relation to each other apart from the name. The C++ compiler will therefore encode the type information in the symbol name, the result being something resembling:

<syntaxhighlight lang="cpp">
int  __f_v () { return 1; }
int  __f_i (int)  { return 0; } 
void __g_v () { int i = __f_v(), j = __f_i(0); }
</syntaxhighlight>

Even though its name is unique, {{code|g()}} is still mangled: name mangling applies to ''all'' C++ symbols (except for those in an <syntaxhighlight lang="cpp" inline>extern "C"{}</syntaxhighlight> block).
