ID3D11DeviceContext::IAGetIndexBuffer method (d3d11.h)
Get a pointer to the index buffer that is bound to the input-assembler stage.
void IAGetIndexBuffer( ID3D11Buffer **pIndexBuffer, DXGI_FORMAT *Format, UINT *Offset );
A pointer to an index buffer returned by the method (see ID3D11Buffer).
Specifies format of the data in the index buffer (see DXGI_FORMAT). These formats provide the size and type of the data in the buffer. The only formats allowed for index buffer data are 16-bit (DXGI_FORMAT_R16_UINT) and 32-bit (DXGI_FORMAT_R32_UINT) integers.
Offset (in bytes) from the start of the index buffer, to the first index to use.
Any returned interfaces will have their reference count incremented by one. Applications should call IUnknown::Release on the returned interfaces when they are no longer needed to avoid memory leaks.
