D3DEXECUTEBUFFERDESC

The D3DEXECUTEBUFFERDESC structure describes the execute buffer for such methods as IDirect3DDevice::CreateExecuteBuffer and IDirect3DExecuteBuffer::Lock.

typedef struct _D3DExecuteBufferDesc { 
    DWORD  dwSize; 
    DWORD  dwFlags; 
    DWORD  dwCaps; 
    DWORD  dwBufferSize; 
    LPVOID lpData; 
} D3DEXECUTEBUFFERDESC, *LPD3DEXECUTEBUFFERDESC;
