addr2line
translates addresses into file names and line numbers.
Given an address in an executable or an offset in a section of a relocatable
object, it uses the debugging information to figure out which file name and
line number are associated with it.
The executable or relocatable object to use is specified with the `-e' option. The default is the file `a.out'. The section in the relocatable object to use is specified with the `-j' option.
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 input, and prints the file name and line number for each
address on standard 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
option is used, then each `FILENAME:LINENO' line is
preceded by a `FUNCTIONNAME' 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.
The long and short forms of options, shown here as alternatives, are equivalent.
