Name

demangle - decode C++ name encoding

Syntax

demangle [ -show_mangled_name ] [ -no_vtable_info ] [ - ] [ file... ]

Description

Function name mangling allows object code to have distinct names for functions that share the same name in the C++ source code and enables type-safe linkage. A name demangler is provided to translate such mangled names into the function names that appear in the source code, so that they are recognizable by the user.

The demangle command reads each file in sequence, demangles any Compaq C++ encoded names, and displays the result on the standard output. If no input file is given, or if a minus sign (-) is encountered as an argument (for example, demangle -), the demangle command reads from the standard input file. The demangle utility supports the processing of 8-bit characters.

Options

-
Read from the standard input file.

-show_mangled_name
Display encoded name in parentheses after demangled name.

-no_vtable_info
Suppress the display of information concerning internal symbols (specifically __vtbl and __btbl).

Examples
