D3D_NAME enumeration (d3dcommon.h)

2022-01-31

Values that identify shader parameters that use system-value semantics.

Note

For programming with Direct3D 10, this API has a type alias that begins D3D10_ instead of D3D_. These Direct3D 10 type aliases are defined in d3d10.h, d3d10misc.h, and d3d10shader.h.
