D3D_SHADER_VARIABLE_TYPE enumeration (d3dcommon.h)

Values that identify various data, texture, and buffer types that can be assigned to a shader variable.

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.

Remarks

A call to the ID3D11ShaderReflectionType::GetDesc method returns a D3D_SHADER_VARIABLE_TYPE value in the Type member of a D3D11_SHADER_TYPE_DESC structure.

The types in a structured buffer describe the structure of the elements in the buffer. The layout of these types generally match their C++ struct counterparts. The following examples show structured buffers:

struct mystruct {float4 val; uint ind;}; RWStructuredBuffer<mystruct> rwbuf;
                                         RWStructuredBuffer<float3> rwbuf2;
