UINT MipSlice;

}

Listing 2.35. The members of the D3D11TEX2D_UAV structure.

The mip-map level is selected with the MipSlice member. The difference from the
shader resource view subresource is that only a single mip-map level is allowed. This is
shown in Figure 2.38.
The array-based 2D texture resources are also able to be exposed to the program-
mable shader programs with an unordered access view. This allows a single mip-map level
to be specified over a subrange of the array elements. These selections are made with the
D3D11_TEX2D_ARRAY_UAV structure in the D3D11_UN0RDERED_ACCESS_VIEW_DESC struc-
ture, as shown in Listing 2.36.

struct D3D11_TEX2D_ARRAY_UAV {
