D3DM_UnlockSurface (Windows CE 5.0)
This function is called by the Direct3D Mobile middleware to remove the locks on surfaces previously locked by calls to D3DM_LockSurface.
typedef DWORD (*D3DM_UNLOCKSURFACE_PTR)(D3DM_UNLOCKSURFACE_DATA *);
Parameters
- D3DM_UNLOCKSURFACE_DATA
[in, out] A pointer to a D3DM_UNLOCKSURFACE_DATA structure describing the surface to unlock.
Return Values
Implement this function so that it returns D3DM_DRIVER_HANDLED when it succeeds and D3DM_DRIVER_NOTHANDLED when it fails.
Remarks
The retail Direct3D Mobile middleware allows unlocking calls from the application to pass through to D3DM_UnlockSurface even if the surface was not previously locked. It is a good practice to detect this case in your driver and return an error value in D3DM_UNLOCKSURFACE_DATA.rval so that value can be passed on to the application.
Requirements
OS Versions: Windows CE 5.0
Header: D3dmddk.h.
Link Library: Developer implemented.
