windbg自带的stl_map等指令不能正确导出stl容器中的数据,网上有个同行写的windbg插件stlkit,用于导出stl map和set的数据
备注:如果是查看std::string类型,不用安装任何插件。直接执行命令 :dt -b 字符串变量名字
查看_Ptr成员就是string字符串的内容。
一、不使用插件查看STL类型
备注:(不使用插件的这种方法,显示map的,这些在windbg 10版本上可以,windbg6.12好像不行)
1、根据map变量名称显示std::map的内容
使用命令:dx map变量名
0:000> dx direct
direct : { size=0x2 } [Type: std::map<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::less<std::basic_string<char,std::char_traits<char>,std::allocator<char> > >,std::allocator<std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > > > >]
[<Raw View>] [Type: std::map<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::less<std::basic_string<char,std::char_traits<char>,std::allocator<char> > >,std::allocator<std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > > > >]

[0x0] : "sanganlei", "hello" [Type: std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > >]

2、根据map地址和类型,显示std::map的内容
a)根据map地址和类型,显示std::map的内容
指令格式:dx @$myvar = ((map类型*)addr)
0:000> dx @$myvar = ((std::map<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::less<std::basic_string<char,std::char_traits<char>,std::allocator<char> > >,std::allocator<std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > > > > * ) 0x00cffec8)
@$myvar = ((std::map<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::less<std::basic_string<char,std::char_traits<char>,std::allocator<char> > >,std::allocator<std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > > > > * ) 0x00cffec8) : 0xcffec8 : { size=0x2 } [Type: std::map<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::less<std::basic_string<char,std::char_traits<char>,std::allocator<char> > >,std::allocator<std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > > > > *]
[<Raw View>] [Type: std::map<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::less<std::basic_string<char,std::char_traits<char>,std::allocator<char> > >,std::allocator<std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > > > >]
[comparator] : less [Type: std::_Compressed_pair<std::less<std::basic_string<char,std::char_traits<char>,std::allocator<char> > >,std::_Compressed_pair<std::allocator<std::_Tree_node<std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > >,void *> >,std::_Tree_val<std::_Tree_simple_types<std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > > > >,1>,1>]
[allocator] : allocator [Type: std::_Compressed_pair<std::allocator<std::_Tree_node<std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > >,void *> >,std::_Tree_val<std::_Tree_simple_types<std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > > > >,1>]
[0x1] : "sanganlei", "hello" [Type: std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > >]
[0x2] : "yuyu", "zhognguo" [Type: std::pair<std::basic_string<char,std::char_traits<char>,std::allocator<char> > const ,std::basic_string<char,std::char_traits<char>,std::allocator<char> > >]
b)接着上一步显示map的second内容,循环次数根据上右边的个数填写。
0:000> .for (r $t0 = 0 ; @$t0 < 5 ; r $t0 = @$t0+1) { dx @$myvar[0][@$t0].second }
0:000> .for (r $t0 = 0 ; @$t0 < 5 ; r $t0 = @$t0+1) { dx @$myvar[0][@$t0].second }
@$myvar[0][@$t0].second : "hello" [Type: std::basic_string<char,std::char_traits<char>,std::allocator<char> >]
[<Raw View>] [Type: std::basic_string<char,std::char_traits<char>,std::allocator<char> >]
[size] : 0x5 [Type: unsigned int]
[capacity] : 0xf [Type: unsigned int]
[allocator] : allocator [Type: std::_Compressed_pair<std::allocator<char>,std::_String_val<std::_Simple_types<char> >,1>]
[0] : 104 'h' [Type: char]
[1] : 101 'e' [Type: char]
[2] : 108 'l' [Type: char]
[3] : 108 'l' [Type: char]
[4] : 111 'o' [Type: char]
二、使用插件的方法查看STL类型
使用方法和下载地址如下:
1.stlkit拷贝到windbg安装路径下的winext目录中;
2.windbg没有自动加载stlkit时,使用.load stlkit指令手动加载。
3.!set或!stlkit.set指令导出STL set的内容(参考图1)
使用方法是:
!set 变量名
!set 地址#成员类型
4.!map或!stlkit.map指令导出STL map的内容(参考图2、图3、图4)
使用方法是:
!map 变量名
!map 地址#map继承的树类型
!map 地址#key_type#value_type
5.注意参数一定用’#’串联;所有类型名最好直接从windbg中复制,windbg对类型名很敏感,即使一个空格的差别都不能识别;
6.插件下载地址(某个):http://download.csdn.net/detail/yichigo/7687719
(图1、set查看的两种方法)
(图2、!map 变量名)
(图3、!map 地址#map继承的树类型)
(图4、!map 地址#key_type#value_type)
(图4、!map 地址#key_type#value_type)
