Members

Name

The name of the function parameter.

SemanticName

The HLSL semantic that is associated with this function parameter. This name includes the index, for example, SV_Target[n].

Type

A D3D_SHADER_VARIABLE_TYPE-typed value that identifies the variable type for the parameter.

Class

A D3D_SHADER_VARIABLE_CLASS-typed value that identifies the variable class for the parameter as one of scalar, vector, matrix, object, and so on.

Rows

The number of rows for a matrix parameter.

Columns

The number of columns for a matrix parameter.

InterpolationMode

A D3D_INTERPOLATION_MODE-typed value that identifies the interpolation mode for the parameter.

Flags

A combination of D3D_PARAMETER_FLAGS-typed values that are combined by using a bitwise OR operation. The resulting value specifies semantic flags for the parameter.

FirstInRegister

The first input register for this parameter.

FirstInComponent

The first input register component for this parameter.

FirstOutRegister

The first output register for this parameter.

FirstOutComponent

The first output register component for this parameter.
