Printing full backtrace in c++
提问by petersohn
I want to dump a backtrace from a C++ program in Linux in a similar format as it is done in gdb. I tried to use the backtrace() and backtrace_symbols() functions for this purpose. These returned function names and offsets. I can use the __cxa_demangle() function to get a readable function name.
我想以与在 gdb 中完成的格式类似的格式从 Linux 中的 C++ 程序转储回溯。为此，我尝试使用 backtrace() 和 backtrace_symbols() 函数。这些返回的函数名称和偏移量。我可以使用 __cxa_demangle() 函数来获取可读的函数名称。
Is there any way to get the file/line positions too, as it is done by gdb?
有没有办法获取文件/行位置，因为它是由 gdb 完成的？

How it's better to invoke gdb from program to print its stacktrace?`
Methode #4, shows a way to get filename and line. But uses a extern program..
Methode #4，显示了一种获取文件名和行的方法。但是使用外部程序..
