- .IX Title "C++FILT 1"
- .TH C++FILT 1 "2005-04-20" "binutils-2.15.97" "GNU Development Tools"
- .SH "NAME"
- c++filt - Demangle C++ and Java symbols.
- .SH "SYNOPSIS"
- .IX Header "SYNOPSIS"
- c++filt [fB-_fR|fB--strip-underscoresfR]
- [fB-jfR|fB--javafR]
- [fB-nfR|fB--no-strip-underscoresfR]
- [fB-pfR|fB--no-paramsfR]
- [fB-sfR fIformatfR|fB--format=fRfIformatfR]
- [fB--helpfR] [fB--versionfR] [fIsymbolfR...]
- .SH "DESCRIPTION"
- .IX Header "DESCRIPTION"
- The *(C+ and Java languages provides function overloading, which means
- that you can write many functions with the same name (providing each
- takes parameters of different types). All *(C+ and Java function names
- are encoded into a low-level assembly label (this process is known as
- &fImanglingfR). The fBc++filtfR
- [1]
- program does the inverse mapping: it decodes (fIdemanglesfR) low-level
- names into user-level names so that the linker can keep these overloaded
- functions from clashing.
- .PP
- 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.
- .PP
- You can use fBc++filtfR to decipher individual symbols:
- .PP
- .Vb 1
- & c++filt <symbol>
- .Ve
- .PP
- If no fIsymbolfR arguments are given, fBc++filtfR reads symbol
- names from the standard input and writes the demangled names to the
- standard output. All results are printed on the standard output.

- .IX Item "-_"
- .PD 0
- .IP "fB--strip-underscoresfR" 4
- .IX Item "--strip-underscores"
- .PD
- On some systems, both the C and *(C+ compilers put an underscore in front
- of every name. For example, the C name f(CW*(C`foo*(C'fR gets the low-level
- name f(CW*(C`_foo*(C'fR. This option removes the initial underscore. Whether
- &fBc++filtfR removes the underscore by default is target dependent.
- .IP "fB-jfR" 4
- .IX Item "-j"
- .PD 0
- .IP "fB--javafR" 4
- .IX Item "--java"

- Prints demangled names using Java syntax. The default is to use *(C+
