D3DXSHADER_CONSTANTTABLE structure

Helper structure for managing a shader constant table. This can also be done using ID3DXConstantTable.

Syntax

typedef struct D3DXSHADER_CONSTANTTABLE {
  DWORD Size;
  DWORD Creator;
  DWORD Version;
  DWORD Constants;
  DWORD ConstantInfo;
  DWORD Flags;
  DWORD Target;
} D3DXSHADER_CONSTANTTABLE, *LPD3DXSHADER_CONSTANTTABLE;

Members

Size

Type: DWORD

Size of the structure. See Remarks.

Creator

Type: DWORD

Offset from the beginning of this structure, in bytes, to the string that contains the name of the creator.

Version

Type: DWORD

Shader version.

Constants

Type: DWORD

Number of constants.

ConstantInfo

Type: DWORD

Array of constant information, D3DXSHADER_CONSTANTINFO[Constants]. See D3DXSHADER_CONSTANTINFO.

Flags

Type: DWORD

The D3DXSHADER Flags flags used to compile the shader.

Target

Type: DWORD

Offset into the string that contains the target.

Remarks

Shader constant information is included in a tab-delimited table of comments. All offsets are measured in bytes from the beginning of the structure. Entries in the constant table are sorted by Creator in ascending order.

A shader constant table can be managed with the ID3DXConstantTable interfaces. Alternatively, you can manage the constant table with D3DXSHADER_CONSTANTTABLE.

This size member is often initialized using the following:

D3DXSHADER_CONSTANTTABLE constantTable;
constantTable.Size = sizeof(D3DXSHADER_CONSTANTTABLE)
