How to migrate ID3D10Texture2D::Map and D3D10_MAPPED_TEXTURE2D

Question

I am porting a Direct3D10 routine that read backbuffer pixels.

ID3D10Texture2D *backBuffer, *copyBuffer;
D3D10_TEXTURE2D_DESC tex2dDesc;
D3D10_MAPPED_TEXTURE2D mapTex;
m_swapChain->GetBuffer(0, __uuidof(ID3D10Texture2D), 
      reinterpret_cast<void**>(&backBuffer));
m_d3dDevice->CreateTexture2D(&tex2dDesc, NULL, &copyBuffer);
copyBuffer->Map(0, D3D10_MAP_READ, 0, &mapTex);
copyBuffer->Unmap(0);

The problem is that ID3D10Texture2D::Map and D3D10_MAPPED_TEXTURE2D are no longer provided in Direct3D11. What are the equivalent functions in Direct3D11, or how to read backbuffer pixels in Direct3D11?

Answer 1

Now you should use ID3D11DeviceContext::Map

C++ DX11

Answer 2

As RaptorCK16 says, use ID3D11DeviceContext::Map.

Differences such as this between D3D10 and D3d11 are documented at Migrating to Direct3D 11.
