Я заставил его работать, используя SymGetTypeFromName, чтобы получить индекс символа, а затем использую SymGetTypeInfo, чтобы получить детали:
const
Index: THandle =1;
Size = (SizeOf(SYMBOL_INFO)-1 + MAX_SYM_NAME * SizeOf(TCHAR) + SizeOf(ULONG64) -1) div SizeOf(ULONG64);
var
Filename: String;
Path: String;
dwBaseAddress: array[0..0] of DWORD;
im: IMAGEHLP_MODULE64;
Buffer: array[0..Size] of ULONG64;
pSymbol: PSYMBOL_INFO;
SymbolName: array[0..MAX_SYM_NAME-1] of Char;
i: Integer;
ChildParams: TI_FINDCHILDREN_PARAMS;
dwOffset: DWORD;
pSymName: PChar;
begin
ZeroMemory(@SymbolName, SizeOf(SymbolName));
SymbolName := '_PEB';
Filename := 'C:\Windows\System32\ntdll.dll';
Path := 'symsrv*symsrv.dll*C:\Symbols*http://msdl.microsoft.com/download/symbols';
{ Initialize }
Win32Check(SymInitialize(Index, nil, False));
{ Register callback to get some debug info }
Win32Check(SymRegisterCallback64(Index, DbgHelpCallback, 0));
{ Set Options }
SymSetOptions(SymGetOptions or SYMOPT_UNDNAME);
SymSetOptions(SymGetOptions or SYMOPT_DEBUG);
SymSetOptions(SymGetOptions or SYMOPT_LOAD_ANYTHING);
{ Set Symbol Path }
Win32Check(SymSetSearchPathW(Index, PChar(Path)));
{ Load Module }
dwBaseAddress[0] := SymLoadModuleExW(Index, 0, PChar(Filename), nil, 0, 0, nil, 0);
ZeroMemory(@im, SizeOf(im));
im.SizeOfStruct := SizeOf(im);
for i := 0 to Length(dwBaseAddress)-1 do
begin
SymGetModuleInfoW64(Index, dwBaseAddress[i], im);
end;
ZeroMemory(@Buffer, SizeOf(Buffer));
pSymbol := PSYMBOL_INFO(@Buffer);
pSymbol^.SizeOfStruct := SizeOf(SYMBOL_INFO);
pSymbol^.MaxNameLen := MAX_SYM_NAME;
{ Get Type Info by Symbol Name (we need the index) }
Win32Check(SymGetTypeFromNameW(Index, dwBaseAddress[0], SymbolName, pSymbol));
{ Get Child Count }
ZeroMemory(@ChildParams, SizeOf(ChildParams));
Win32Check(SymGetTypeInfo(Index, dwBaseAddress[0], pSymbol^.TypeIndex, TI_GET_CHILDRENCOUNT, @ChildParams.Count));
{ Get Child Info }
// TODO: Caller must reserve memory for the ChildId array (Count * SizeOf(ULONG))
Win32Check(SymGetTypeInfo(Index, dwBaseAddress[0], pSymbol^.TypeIndex, TI_FINDCHILDREN, @ChildParams));
for i := ChildParams.Start to ChildParams.Count - 1 do
begin
{ Get Child Name }
Win32Check(SymGetTypeInfo(Index, dwBaseAddress[0], {pSymbol^.TypeIndex + }ChildParams.ChildId[i], TI_GET_SYMNAME, @pSymName));
{ Get Child Offset }
Win32Check(SymGetTypeInfo(Index, dwBaseAddress[0], {pSymbol^.TypeIndex + }ChildParams.ChildId[i], TI_GET_OFFSET, @dwOffset));
Memo1.Lines.Add(Format('+0x%.3x %s', [dwOffset, pSymName]));
LocalFree(Cardinal(pSymName));
end;
for i := 0 to Length(dwBaseAddress)-1 do
begin
Win32Check(SymUnloadModule64(Index, dwBaseAddress[i]));
end;
Win32Check(SymCleanup(Index));
end;

Теперьперейдите к следующему шагу: используйте RTTI Delphi 2010 и используйте этот механизм для сравнения смещений (это помогает мне конвертировать заголовки для Jedi ApiLib).
