This behaviour is because when the names are read from the standard input it This command however will work:Įcho _Z1fv, | c++filt -nand will display 'f(),', i.e., the demangled name followed by a trailing comma. (Note the extra comma at the end of the mangled name which makes it invalid).

Thus for example:Ĭ++filt -n _Z1fvwill work and demangle the name to 'f()' whereas:Ĭ++filt -n _Z1fv,will not work. The difference between reading names from the command line versus reading names from the standard input is that command line arguments are expected toīe just mangled names and no checking is performed to separate them from surrounding text. All the results are printed on the standard You can also use c++filt to decipher individual symbols by passing them on the command line:Ĭ++filt If no symbol arguments are given, c++filt reads symbol names from the standard input instead. In this way youĬan pass an entire assembler source file, containing mangled names, through c++filt and see the same source file containing demangled names. Into a C ++ name, the C ++ name replaces the low-level name in the output, otherwise the original word is output. The inverse mapping: it decodes ( demangles) low-level names into user-level names so that they can be read.Įvery alphanumeric word (consisting of letters, digits, underscores, dollars, or periods) seen in the input is a potential mangled name. Into a low-level assembler name which uniquely identifies each different version. In order to be able to distinguish these similarly named functions C ++ and Java encode them

The C ++ and Java languages provide function overloading, which means that you can write many functions with the same name, providing thatĮach function takes parameters of different types.
