问题：
I am running an application through gdb and I want to set a breakpoint for any time a specific variable is accessed / changed.我正在通过 gdb 运行一个应用程序，我想在任何时候访问/更改特定变量时设置一个断点。 Is there a good method for doing this?有没有好的方法可以做到这一点？ I would also be interested in other ways to monitor a variable in C/C++ to see if/when it changes.我也对在 C/C++ 中监视变量以查看它是否/何时更改的其他方法感兴趣。
