IDirect3DIndexBuffer9 interface (d3d9helper.h)
Applications use the methods of the IDirect3DIndexBuffer9 interface to manipulate an index buffer resource.
Inheritance
The IDirect3DIndexBuffer9 interface inherits from IDirect3DResource9. IDirect3DIndexBuffer9 also has these types of members:
Methods
The IDirect3DIndexBuffer9 interface has these methods.
| IDirect3DIndexBuffer9::GetDesc The IDirect3DIndexBuffer9::GetDesc method (d3d9helper.h) retrieves a description of the index buffer resource. |
| IDirect3DIndexBuffer9::Lock The IDirect3DIndexBuffer9::Lock method (d3d9helper.h) locks a range of index data and obtains a pointer to the index buffer memory. |
| IDirect3DIndexBuffer9::Unlock The IDirect3DIndexBuffer9::Unlock method (d3d9helper.h) unlocks index data. |
Remarks
The IDirect3DIndexBuffer9 interface is obtained by calling the IDirect3DDevice9::CreateIndexBuffer method.
This interface inherits additional functionality from the IDirect3DResource9 interface.
This interface, like all COM interfaces, inherits from the IUnknown interface.
The LPDIRECT3DINDEXBUFFER9 and PDIRECT3DINDEXBUFFER9 types are defined as pointers to the IDirect3DIndexBuffer9 interface.
typedef struct IDirect3DIndexBuffer9 *LPDIRECT3DINDEXBUFFER9, *PDIRECT3DINDEXBUFFER9;
