6.8.2 Constant Buffer Information

As previously mentioned, the ID3DllShaderReflection interface can be used to obtain an
ID3DllShaderReflectionConstantBuffer interface containing information for a constant
buffer used in a shader program. This is done by calling either GetConstantBufferByName,
or GetConstantBufferBylndex. The former accepts a string parameter, and is useful if an
application has prior knowledge of a shader program and simply needs to query a few spe-
cific details. The latter is more useful when dealing with an unknown shader program, as
it allows enumeration of all constant buffers. The number of constant buffers in a program
is provided by the D3D11_SHADER_DESC structure returned by GetDesc. Listing 6.25 dem-
onstrates the common pattern of retrieving the number of constant buffers, and iterating
through the ID3DllShaderReflectionConstantBuffer interfaces.
