D3D_SHADER_MACRO Structure

Defines a shader macro.

Syntax

typedef struct _D3D_SHADER_MACRO {
    LPCSTR Name;
    LPCSTR Definition;
} D3D_SHADER_MACRO, *LPD3D_SHADER_MACRO;  

Members

Name
The macro name.

Definition
The macro definition.

Remarks

You can use shader macros in your shaders. The D3D_SHADER_MACRO structure defines a single shader macro as shown in the following example:

D3D_SHADER_MACRO Shader_Macros[1] = { "zero", "0"  };  

The following shader or effect creation functions take an array of shader macros as an input parameter:

• D3D10CompileShader
• D3DX10CreateEffectFromFile
• D3DX10PreprocessShaderFromFile
• D3DX11CreateAsyncShaderPreprocessProcessor

Requirements

Header: Declared in d3d11_x.h (d3dcommon.h on other Windows platforms).
