在c ++中打印完整的backtrace [英] Printing full backtrace in c++

问题描述

我想从一个C ++程序在Linux中转储一个类似于gdb中的格式的回溯。我试图使用backtrace（）和backtrace_symbols（）函数为此目的。这些返回的函数名和偏移量。我可以使用__cxa_demangle（）函数来获取可读的函数名。

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.

有没有办法获取文件/行位置，就像gdb做的？

Is there any way to get the file/line positions too, as it is done by gdb?
