Members

Name

Type: LPCSTR

The name of the function parameter.

SemanticName

Type: LPCSTR

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

Type

Type: D3D_SHADER_VARIABLE_TYPE

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

Class

Type: D3D_SHADER_VARIABLE_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

Type: UINT

The number of rows for a matrix parameter.

Columns

Type: UINT

The number of columns for a matrix parameter.

InterpolationMode

Type: D3D_INTERPOLATION_MODE

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

Flags

Type: D3D_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

Type: UINT

The first input register for this parameter.

FirstInComponent

Type: UINT

The first input register component for this parameter.

FirstOutRegister

Type: UINT

The first output register for this parameter.

FirstOutComponent

Type: UINT

The first output register component for this parameter.
