mangled name

mangled name
 n.

   A name, appearing in a C++ object file, that is a coded representation
   of the object declaration as it appears in the source. Mangled names
   are used because C++ allows multiple objects to have the same name, as
   long as they are distinguishable in some other way, such as by having
   different parameter types. Thus, the internal name must have that
   additional information embedded in it, using the limited character set
   allowed by most linkers. For instance, one popular compiler encodes
   the standard library function declaration "memchr(const
   void*,int,unsigned int)" as "@memchr$qpxviui".
