I'm trying to print an object's vtable using gdb; I found the

上的

show print vt bl on

setting, but I still don't actually know how to print the vtable - p *object still doesn't print it out.

如何打印vtable？

How do I print the vtable?

答


  (gdb) set $i = 0
  (gdb) while $i < 10
     >print $i
     >p /a (*(void ***)obj)[$i]
     >set $i = $i + 1
     >end

其中obj是您要打印的vtable的对象，10是方法数。

Where "obj" is the object whose vtable you'd like to print, and 10 is the number of methods.
