NAME

c++filt — decode C++ symbols

SYNOPSIS

c++filt

[--help] [-_ | --strip-underscores] [-n | --no-strip-underscores] [-p | --no-params] [-s scheme | --format=scheme] [-V | --version] [encoded-names ...]

DESCRIPTION

The c++filt utility translates encoded C++ symbol names to human-readable form. The c++filt utility has two operating modes.

• If arguments encoded-names are not specified, then c++filt will act as a filter, reading from standard input and writing to standard output.
• If arguments encoded-names are specified, then c++filt will decode each such argument in turn, writing its decoded form to standard output.

The c++filt utility recognizes the following options:

 

 

--help

Print a help message and exit.

 

 

-_ | --strip-underscores

Remove a leading underscore from symbol names prior to decoding them.

 

 

-n | --no-strip-underscores

Do not remove leading underscores from names.

 

 

-p | --no-params

This option is recognized but ignored.

 

 

-s scheme | --format=scheme

Select the encoding scheme to use. Argument scheme can be one of the following:

 

 

arm

Use the encoding scheme specified by the C++ Annotated Reference Manual.

 

 

auto

Guess the encoding scheme from the input.

 

 

gnu

Use the encoding scheme used by the GNU C++ compiler.

 

 

gnu-v3

Use the encoding scheme used by the GNU C++ compiler, version 3.

 

 

-V | --version

Print a version identifier for c++filt and exit.

EXIT STATUS

The c++filt utility exits 0 on success, and >0 if an error occurs.
