NtGdiDxgGenericThunk( ULONG_PTR ulIndex, ULONG_PTR ulHandle, SIZE_T *pdwSizeOfPtr1, PVOID pvPtr1, SIZE_T *pdwSizeOfPtr2, PVOID pvPtr2)
The function NtGdiDxgGenericThunk redirects DirectX calls to another function.
Redirection is done in dxg.sys in XP or higher. If dxg.sys does not exist, redirection takes place in win32k.sys
Parameters
- ULONG_PTR ulIndex
The functions we want to redirect
- ULONG_PTR ulHandle
Unknown
- SIZE_T *pdwSizeOfPtr1
Unknown
- PVOID pvPtr1
Unknown
- SIZE_T *pdwSizeOfPtr2
Unknown
