  [in]            LPCVOID  pSrcData,
  [in]            SIZE_T   SrcDataSize,
  [in]            UINT     uNumShaders,
  [in]            UINT     uStartIndex,
  [in, optional]  UINT     *pIndices,
  [in]            UINT     uFlags,

  [out, optional] UINT     *pTotalShaders
);

Parameters

[in] pSrcData

Type: LPCVOID

A pointer to uncompiled shader data; either ASCII HLSL code or a compiled effect.

[in] SrcDataSize

Type: SIZE_T

Length of uncompiled shader data that pSrcData points to.

[in] uNumShaders

Type: UINT

The number of shaders to decompress.

[in] uStartIndex

Type: UINT

The index of the first shader to decompress.

[in, optional] pIndices

Type: UINT*

An array of indexes that represent the shaders to decompress.

[in] uFlags

Type: UINT

Flags that indicate how to decompress. Currently, no flags are defined.

[out] ppShaders

Type: ID3DBlob**

The address of a pointer to the ID3DBlob interface that is used to retrieve the decompressed shader data.

[out, optional] pTotalShaders

Type: UINT*

A pointer to a variable that receives the total number of shaders that D3DDecompressShaders decompressed.

Return value
