In this +mode, +.B 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 +.B \-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, +.B addr2line +will print two question marks in their place.
