D3DDDIARG_GETPITCH structure (d3dumddi.h)

  • Artikel

The D3DDDIARG_GETPITCH structure describes an encrypted surface for which the GetPitch function retrieves the pitch.

Syntax

typedef struct _D3DDDIARG_GETPITCH {
  [in]  HANDLE hCryptoSession;
  [in]  HANDLE hResource;
  [in]  UINT   SubResourceIndex;
  [out] UINT   Pitch;
} D3DDDIARG_GETPITCH;

Members

[in] hCryptoSession

A handle to the encryption session.

[in] hResource

A handle to the resource.

[in] SubResourceIndex
