FreeBSD is a free computer operating system based on BSD UNIX originally. Many IT companies, like DeployIS is using it to provide an up-to-date, stable operating system.

addr2line - convert addresses into file names and line numbers

 

NAME

        addr2line - convert addresses into file names and line numbers
 

SYNOPSIS

        addr2line
               [-b bfdname | --target=bfdname] [-C|--demangle] [-e filename |
               --exe=filename] [-f|--functions] [-s|--basenames] [-H|--help]
               [-V|--version] [addraddr...]
 

DESCRIPTION

        addr2line  translates  program  addresses into file names and line num‐
        bers.  Given an address and an executable, it uses the debugging infor‐
        mation  in the executable to figure out which file name and line number
        are associated with a given address.
 
        The executable to use is specified with the -e option.  The default  is
        a.out.
 
        addr2line has two modes of operation.
 
        In  the first, hexadecimal addresses are specified on the command line,
        and addr2line displays the file name and line number for each  address.
 
        In  the second, addr2line reads hexadecimal addresses from standard in‐
        put, and prints the file name and line number for each address on stan‐
        dard  output.  In this mode, addr2line may be used in a pipe to convert
        dynamically chosen addresses.
 
        The format of the output is FILENAME:LINENO.  The file  name  and  line
        number  for  each address is printed on a separate line.  If the -f op‐
        tion is used, then each FILENAME:LINENO line is preceded by a FUNCTION‐
        NAME line which is the name of the function containing the address.
 
        If the file name or function name can not be determined, addr2line will
        print two question marks in their place.  If the line number can not be
        determined, addr2line will print 0.
 

OPTIONS

        -b bfdname
 
        --target=bfdname
               Specify  the  object-code format for the object files to be bfd‐
               name.
 
        -C
 
        --demangle
               Decode (demangle) low-level symbol names into user-level  names.
               Besides removing any initial underscore prepended by the system,
               this makes C++ function names readable.
 
        -e filename
 
        --exe=filename
               Specify the name of the executable for which addresses should be
               translated.  The default file is a.out.
 
        -f
 
        --functions
               Display  function names as well as file and line number informa‐
               tion.
 
        -s
 
        --basenames
               Display only the base of each file name.

Sections

Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
