I'm currently dumping a lot of information from a PDB file I retrieve using the DIA SDK to an XML file so that I can then use that information to display stuff about the structure of the project etc.
For naming the XML nodes, I have a trivial function that translates the value of the enum to a string which is then used for the node:
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;
}
This function encompasses all values listed here: http://msdn.microsoft.com/de-de/library/bkedss5f.aspx
Now, for dumping the DIA information, I basically just recurse down the children of all symbols I get using pGlobal->findChildren(SymTagUDT, NULL, nsCaseSensitive, &pIDiaEnumSymbols)
. The curious part is that the resulting XML contains a lot of stuff that looks like this:
<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>
Now, nevermind the empty name information and stuff, that's all pretty unfinished so far. I'd just really like to know what kind of symbol has a symTag of 31. The enumerator seems to contain 31 elements, so values from 0 to 30 should be valid. Does anybody have any idea what this 31 could be? The function in question looks like this:
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;
}
}
It's part of the SystemC fifo example project. Nothing too fancy, really.
