DIA SDK SymTagEnum值

Question

我目前正在从使用DIA SDK检索到的XML文件的PDB文件中转储大量信息，以便我可以使用该信息显示有关项目结构的内容等。

为了命名XML节点，我有一个简单的函数，它将枚举的值转换为一个字符串，然后用于节点：

string symTagTypeToString(DWORD type) {

string symTagTypename = "";

switch(type) {
case SymTagNull:
    symTagTypename = "null";
    break;
case SymTagExe:
    symTagTypename = "exe";
    break;
case SymTagCompiland:
    symTagTypename = "compiland";
    break;
case SymTagCompilandDetails:
    symTagTypename = "compilandDetails";
    break;
case SymTagCompilandEnv:
    symTagTypename = "compilandEnvironmentVar";
    break;
case SymTagFunction:
    symTagTypename = "function";
    break;
case SymTagBlock:
    symTagTypename = "block";
    break;
case SymTagData:
    symTagTypename = "data";
    break;
case SymTagAnnotation:
    symTagTypename = "annotation";
    break;
case SymTagLabel:
    symTagTypename = "label";
    break;
case SymTagPublicSymbol:
    symTagTypename = "publicSymbol";
    break;
case SymTagUDT:
    symTagTypename = "userDefinedType";
    break;
case SymTagEnum:
    symTagTypename = "enumerator";
    break;
case SymTagFunctionType:
    symTagTypename = "functionType";
    break;
case SymTagPointerType:
    symTagTypename = "pointer";
    break;
case SymTagArrayType:
    symTagTypename = "array";
    break;
case SymTagBaseType:
    symTagTypename = "baseType";
    break;
case SymTagTypedef:
    symTagTypename = "typedef";
    break;
case SymTagBaseClass:
    symTagTypename = "baseClass";
    break;
case SymTagFriend:
    symTagTypename = "friend";
    break;
case SymTagFunctionArgType:
    symTagTypename = "functionArgumentType";
    break;
case SymTagFuncDebugStart:
    symTagTypename = "funcDebugStart";
    break;
case SymTagFuncDebugEnd:
    symTagTypename = "funcDebugEnd";
    break;
case SymTagUsingNamespace:
    symTagTypename = "usingNamespace";
    break;
case SymTagVTableShape:
    symTagTypename = "vTableShape";
    break;
case SymTagVTable:
    symTagTypename = "vTable";
    break;
case SymTagCustom:
    symTagTypename = "custom";
    break;
case SymTagThunk:
    symTagTypename = "thunk";
    break;
case SymTagCustomType:
    symTagTypename = "customType";
    break;
case SymTagManagedType:
    symTagTypename = "managedType";
    break;
case SymTagDimension:
    symTagTypename = "dimension";
    break;
default:
    ostringstream s;
    s << "other" << type;
    symTagTypename = s.str();
    break;
}

return symTagTypename;
}

此功能包含此处列出的所有值：http://msdn.microsoft.com/de-de/library/bkedss5f.aspx

现在，为了转储DIA信息，我基本上只使用pGlobal->findChildren(SymTagUDT, NULL, nsCaseSensitive, &pIDiaEnumSymbols)递归所有符号的子项。奇怪的是，生成的XML包含很多看起来像这样的东西：

<function name="consumer::main">
  <funcDebugStart name="unknown">
  </funcDebugStart>
  <funcDebugEnd name="unknown">
  </funcDebugEnd>
  <data name="">
  </data>
  <data name="">
  </data>
  <data name="">
  </data>
  <data name="this">
  </data>
  <data name="c">
  </data>
  <other31 name="unknown">
  </other31>
  <other31 name="unknown">
  </other31>
  <other31 name="unknown">
  </other31>
  <other31 name="unknown">
  </other31>
  <other31 name="unknown">
  </other31>
  <other31 name="unknown">
  </other31>
  <other31 name="unknown">
  </other31>
  <other31 name="unknown">
  </other31>
 </function>

现在，永远不要忘记空名称信息和内容，到目前为止还没有完成。我真的很想知道什么样的符号有 symTag 31 。枚举器似乎包含31个元素，因此0到30之间的值应该是有效的。有谁知道这31可能是什么？有问题的功能如下：

 void main()
 {
   char c;
   cout << endl << endl;

   while (true) {
     in->read(c);
     cout << c << flush;

     if (in->num_available() == 1)
   cout << "<1>" << flush;
     if (in->num_available() == 9)
   cout << "<9>" << flush;
   }
 }

它是SystemC fifo示例项目的一部分。没什么太奇特的，真的。

在VS2010附带的DIA SDK版本中，添加了两个SymTagEnum值SymTagCallSite和SymTagMax（尽管它们尚未包含在文档中）。虽然我对这些价值所代表的语义仍然没有真正的了解，但这无疑解释了我所获得的价值观。
