可以看到,context函数所显示的信息远比您通常使用缺省 GDBhook_stop函数所看到的信息更详细。(您还会注意到,现在也可以访问数据段了。)使用这些 GDB 增强,您可以看到每次到达断点和执行每步操作时的确切 CPU 状态。单步执行每个命令并观察寄存器和内存值如何受影响,这也是学习 Intel 机器语言命令基础知识的理想方法。 ...

hook及hookpost即表示在某个指令的前后。后面的指令一定要使用GDB指令的全写,如上面就不能写成define hook-b或define hookpost-b。 *如果需要更为详细的资料,请参考GDB Manual,20. Extending GDB (2)在GDB环境可以直接调用python,如在GDB环境下执行python print 23 ...
Players investigate a gripping mystery using Batman’s gadgets, including the Batarang, forensic scanner, and grappling hook. Gotham’s atmosphere is beautifully recreated, making the world feel alive despite the game’s linear nature. The VR mechanics work well, allowing players to interact with ob...
当程序收到SIGSEGV信号时,可以使用gdb自动附加进程,让开发者能够快速定位问题。具体操作是在程序启动时,通过命令行参数指定gdb,并在gdb中设置钩子(hook),当收到SIGSEGV信号时,自动附加进程并进入调试模式。 例如,假设程序名为a.out,可以使用以下命令启动程序并自动附加gdb: ...
