用dt命令搜索查看符号

使用WinDgb调试的时候，我们需要和各种结构体等符号打交道。包括系统的符号等等。有时候符号太多了，我们根本记不住或者只有模糊的印象，比如只记得其中的2个字母，怎么办？或者知道符号名，但不知道在哪个模块，特别是使用stl库的时候。这时候dt搜索就可以帮上忙了。
使用如下通配符命令即可列出所有的符号

dt  *!*XXX*  xxx为我们知道的仅有符号名字符

例如：

0:006> dt  *!*filesystem_error*
          xxx!filesystem_error
          xxx!std::tr2::sys::basic_filesystem_error<std::tr2::sys::basic_path<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::tr2::sys::path_traits> >
          xxx!std::tr2::sys::basic_filesystem_error<std::tr2::sys::basic_path<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::tr2::sys::path_traits> >
          MSVCP120!filesystem_error
          MSVCP120!std::tr2::sys::basic_filesystem_error<std::tr2::sys::basic_path<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::tr2::sys::path_traits> >
          MSVCP120!std::tr2::sys::basic_filesystem_error<std::tr2::sys::basic_path<std::basic_string<char,std::char_traits<char>,std::allocator<char> >,std::tr2::sys::path_traits> >
