器：gdb 循环输出链表值直接固定成脚本命令

 

 gdb 调试模式下，循环输出

(gdb) set $x=13
(gdb) while $x--
 >p $x
 >end
$6 = 12
$7 = 11
$8 = 10
$9 = 9
$10 = 8
$11 = 7
$12 = 6
$13 = 5
$14 = 4
$15 = 3
$16 = 2
$17 = 1
$18 = 0

 

 

实际用起来：

真是打击啊，，，

(gdb) set $x=13
(gdb) while $x--
 >set $PCur=0x614c20
 >set $data=$PCur->mData
 >p $data
 >set $PCur=PCur->mNext
 >end
Attempt to extract a component of a value that is not a structure pointer.
(gdb) set $x=13
(gdb) while $x--
 >if(PCur->mData)
  >PCur=PCur->mNext
  >p PCur->mData
  >end
 >end
(gdb) 

 

nm

我的锅，要set啦！！！
