All C++ function names are encoded into a low-level assembly label (this process is known as mangling). The c++filt program does the inverse mapping: it decodes (demangles) low-level names into user-level names so that the linker can keep these overloaded functions from clashing. Every alphanumeric word (consisting of letters, digits, underscores, dollars, or periods) seen in the input is a potential label. If the label decodes into a C++ name, the C++ name replaces the low-level name in the output. You can use c++filt to decipher individual symbols: c++filt symbol If no symbol arguments are given, c++filt reads symbol names from the standard input and writes the demangled names to the standard output. All results are printed on the standard output.   -_ --strip-underscores On some systems, both the C and C++ compilers put an underscore in front of every name. For example, the C name, foo, gets the low-level name, _foo. This option removes the initial underscore. Whether c++filt removes the underscore by default is target dependent. -n --no-strip-underscores Do not remove the initial underscore. -s format --format=format GNU nm can decode three different methods of mangling, used by different C++ compilers. The argument to this option selects which method it uses: gnu The one used by the GNU compiler (the default method).   lucid The one used by the Lucid compiler.   arm The one specified by the C++ Annotated Reference Manual. --help Print a summary of the options to c++filt and exit. --version Print the version number of c++filt and exit. Warning: c++filt is a new utility, and the details of its user interface are subject to change in future releases. In particular, a command-line option may be required in the future to decode a name passed as an argument on the command line; for example, c++filt symbol may in a future release become c++filt option symbol.
