IMultiLanguage2::DetectCodepageInIStream method

Detects the code page of the given stream.

Syntax


HRESULT DetectCodepageInIStream(
  [in]      DWORD              dwFlag,
  [in]      DWORD              dwPrefWinCodePage,
  [in]      IStream            *pstmIn,
  [in, out] DetectEncodingInfo *lpEncoding,
  [in, out] INT                *pnScores
);

Parameters

dwFlag [in]

One of the MLDETECTCP-defined bit flag values that specify the type of incoming source text. Setting the bit flags helps the detection engines produce more accurate results.

dwPrefWinCodePage [in]

The preferred Windows code page. If this value is set to zero, this API returns all possible encodings. Otherwise, it lists only those encodings related to this parameter.

pstmIn [in]

A pointer to the IStream interface for the source stream.

lpEncoding [in, out]

A pointer to an array of DetectEncodingInfo structures where the detection information will be returned.

pnScores [in, out]

A pointer to a buffer that contains the number of DetectEncodingInfo structures allocated in lpEncoding. When this method is successful, this parameter returns the number of elements of lpEncoding that are filled in.

Return value

Returns one of the following values.

Return codeDescription
S_OK

Success.

S_FALSE

E_FAIL

An error occurred.

 

Remarks

The caller is responsible for allocating and freeing the lpEncoding array.
