D3DM_LockSurface (Windows CE 5.0)
This function is used by the Direct3D Mobile middleware to lock surfaces.
typedef DWORD (*D3DM_LOCKSURFACE_PTR)(D3DM_LOCKSURFACE_DATA *);
Parameters
- D3DM_LOCKSURFACE_DATA
[in, out] A pointer to a D3DM_LOCKSURFACE_DATA structure describing the properties of the lock requested by the middleware.
Return Values
Implement this function so that it returns D3DM_DRIVER_HANDLED when it succeeds and D3DM_DRIVER_NOTHANDLED when it fails.
Remarks
The driver must ensure that a surface's contents remain coherent while a surface is locked. This may require the rendering pipeline to be flushed or stalled if the surface is, for example, a back buffer or depth buffer.
The Direct3D Mobile middleware removes locks on surfaces by calling D3DM_UnlockSurface.
Requirements
OS Versions: Windows CE 5.0
Header: D3dmddk.h.
Link Library: Developer implemented.
