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;
