source code for 多開
看了懂了 就修改下列function 即可bool EnableMultiMS()
{
int handleCount = 1024;
HMODULE ntdll = GetModuleHandle(L"ntdll");
if (ntdll == NULL)
{
Log(L"Couldn't get ntdll handle\n");
return false;
}
NtQueryObject_t ntQO = (NtQueryObject_t)GetProcAddress(ntdll, "NtQueryObject");
NtQuerySystemInformation_t ntQSI = (NtQuerySystemInformation_t)GetProcAddress(ntdll, "NtQuerySystemInformation");
if (ntQO == NULL || ntQSI == NULL)
{
Log(L"Couldn't find procedures for MultiMS (%x / %x)\n", ntQO, ntQSI);
return false;
}
struct HandleInfoSet
{
unsigned int count;
SYSTEM_HANDLE_INFORMATION handles;
};
HandleInfoSet *infoSet = (HandleInfoSet *)malloc(4 + sizeof(SYSTEM_HANDLE_INFORMATION) * handleCount);
DWORD length;
NTSTATUS status = ntQSI((SYSTEM_INFORMATION_CLASS)16, infoSet, 4 + sizeof(SYSTEM_HANDLE_INFORMATION) * handleCount, &length);
Log(L"alloc with %i // %i\n", handleCount, handleCount * sizeof(SYSTEM_HANDLE_INFORMATION) + 4);
while (status == 0xc0000004 /*STATUS_INFO_LENGTH_MISMATCH*/)
{
free(infoSet);
handleCount *= 2;
Log(L"alloc with %i // %i\n", handleCount, handleCount * sizeof(SYSTEM_HANDLE_INFORMATION) + 4);
infoSet = (HandleInfoSet *)malloc(4 + sizeof(SYSTEM_HANDLE_INFORMATION) * handleCount);
status = ntQSI((SYSTEM_INFORMATION_CLASS)16, infoSet, 4 + sizeof(SYSTEM_HANDLE_INFORMATION) * handleCount, &length);
}
if (status != 0 /*STATUS_SUCCESS*/)
{
Log(L"Failed to enumerate handles open by this process (errorcode %x)\n", status);
free(infoSet);
return false;
}
for (unsigned int i = 0; i < infoSet->count; i++)
{
wchar_t nameBuffer;
if (infoSet->handles.handle == 0x0012019F) continue; // some buggy thing we need to skip
status = ntQO((HANDLE)infoSet->handles.handle, (OBJECT_INFORMATION_CLASS)1, nameBuffer, 1024, &length);
if (status != 0 /*STATUS_SUCCESS*/)
continue;
if (wcsstr(nameBuffer + 4, L"WvsClientMtx") != NULL)
{
HANDLE handle;
DuplicateHandle(GetCurrentProcess(), (HANDLE)infoSet->handles.handle, 0, &handle, 0, FALSE, DUPLICATE_CLOSE_SOURCE);
CloseHandle(handle);

break;
}
}
free(infoSet);
return true;
}
很明顯現在的版本沒有那麼簡單了。。。
