将地址转换为 PyKD 可以使用的数字/相当于 WinDbg 的数字?命令 [英] Convert address into a number that PyKD can work with / equivalent of the WinDbg ? command

问题描述

在 WinDbg 中，我有几个选项来定义数字

0:006>?17评估表达式:23 = 000000170:006>?0x17评估表达式:23 = 000000170:006>?0n23评估表达式:23 = 000000170:006>?ntdll评估表达式:2004549632 = 777b00000:006>?ntdll+100评估表达式:2004549888 = 777b01000:006>?ntdll!NtCreateThreadEx评估表达式:2005018944 = 778229400:006>?0t755评估表达式:493 = 000001ed0:006>?0y1111评估表达式:15 = 0000000f

我正在寻找等效的 PyKD，以将所有这些可能性用作我的脚本的输入.

即:我在 sys.argv[1] 中得到一个字符串，它可以是上述任何一种格式，我需要将其转换为 PyKD 可以理解的地址.>

我已经尝试过:

from pykd import *地址 = addr64(sys.argv[1])

解决方案

PyKd 命令是 expr().

<块引用>

expr( (str)expression [, (bool)cplusplus]) -> 对象:

评估windbg表达式

该命令甚至会考虑使用 n 命令在 WinDbg 中设置的数字基数.

要模拟WinDbg的?行为，可以使用

print("求值表达式:", expr(sys.argv[1]), "=", hex(expr(sys.argv[1])), sep=" ")

In WinDbg, I have several options to define a number

0:006> ? 17
Evaluate expression: 23 = 00000017
0:006> ? 0x17
Evaluate expression: 23 = 00000017
0:006> ? 0n23
Evaluate expression: 23 = 00000017
0:006> ? ntdll
Evaluate expression: 2004549632 = 777b0000
0:006> ? ntdll+100
Evaluate expression: 2004549888 = 777b0100
0:006> ? ntdll!NtCreateThreadEx
Evaluate expression: 2005018944 = 77822940
0:006> ? 0t755
Evaluate expression: 493 = 000001ed
0:006> ? 0y1111
Evaluate expression: 15 = 0000000f

I am looking for the PyKD equivalent to use all these possibilities as an input for my script.

That is: I get a string in sys.argv[1] which could be in any of the above mentioned formats and I need to convert it into an address that PyKD can understand.

I have tried:

from pykd import *
address = addr64(sys.argv[1])

解决方案

The PyKd command is expr().

expr( (str)expression [, (bool)cplusplus]) -> object :

Evaluate windbg expression

The command will even consider the number base that has been set in WinDbg using the n command.

To simulate WinDbg's ? behavior, you can use

print("Evaluate expression:", expr(sys.argv[1]), "=", hex(expr(sys.argv[1])), sep=" ")
