D3DDDICB_UNLOCK structure (d3dumddi.h)

The D3DDDICB_UNLOCK structure describes allocations to unlock.

Syntax

typedef struct _D3DDDICB_UNLOCK {
  [in] UINT                NumAllocations;
  [in] const D3DKMT_HANDLE *phAllocations;
} D3DDDICB_UNLOCK;

Members

[in] NumAllocations

The number of allocations in the array that is specified by phAllocations.

[in] phAllocations

An array of D3DKMT_HANDLE data types that represent kernel-mode handles to the allocations. The Microsoft Direct3D runtime's pfnAllocateCb function returns these handles. Therefore, the user-mode display driver uses these handles to unlock the allocations.
