Return code Description
STATUS_SUCCESS Notification about unlocking a shared primary surface was successfully performed.
STATUS_INVALID_PARAMETER Parameters were validated and determined to be incorrect.

This function might also return other NTSTATUS values.

Remarks

The OpenGL ICD calls the D3DKMTSharedPrimaryUnLockNotification function to inform the operating system that an application just unlocked the GDI shared primary surface that exists on the graphics adapter and video present source that the AdapterLuid and VidPnSourceId members of the D3DKMT_SHAREDPRIMARYUNLOCKNOTIFICATION structure specify. The OpenGL ICD should call D3DKMTSharedPrimaryUnLockNotification after it calls the D3DKMTUnlock function to unlock the GDI shared primary surface.
