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; 
typedef D3DEXECUTEBUFFERDESC *LPD3DEXECUTEBUFFERDESC; 
 

Members

dwSize

Size of this structure, in bytes. This member must be initialized before the structure is used.

dwFlags

Flags identifying the members of this structure that contain valid data.

D3DDEB_BUFSIZE	The dwBufferSize member is valid.
D3DDEB_CAPS	The dwCaps member is valid.
D3DDEB_LPDATA	The lpData member is valid.

dwCaps

Location in memory of the execute buffer.

D3DDEBCAPS_MEM
	A logical OR of D3DDEBCAPS_SYSTEMMEMORY and D3DDEBCAPS_VIDEOMEMORY.
D3DDEBCAPS_SYSTEMMEMORY
	The execute buffer data resides in system memory.
D3DDEBCAPS_VIDEOMEMORY
	The execute buffer data resides in device memory.

dwBufferSize

Size of the execute buffer, in bytes.

lpData

Address of the buffer data.
