The syntax for invoking the C++ name demangler is:
| dem2000 [options ] [filenames] |
| dem2000 | Command that invokes the C++ name demangler. |
| options | Options affect how the name demangler behaves. Options can appear anywhere on the command line. (Options are discussed in Section 9.2.) |
| filenames | Text input files, such as the assembly file output by the compiler, the assembler listing file, the disassembly file, and the linker map file. If no filenames are specified on the command line, dem2000 uses standard input. |
By default, the C++ name demangler outputs to standard output. You can use the -o file option if you want to output to a file.
