IMultiLanguage::ConvertStringFromUnicode method

Translates the source Unicode string to the specified multibyte code page.

Syntax


HRESULT ConvertStringFromUnicode(
  [in, out]  DWORD *pdwMode,
  [in]       DWORD dwEncoding,
  [in]       WCHAR *pSrcStr,
  [in, out]  UINT *pcSrcSize,
  [in]       __wchar_t *pDstStr,
  [in, out]  UINT *pcDstSize
);

Parameters

pdwMode [in, out]

The storage for conversion context. A calling function should provide only storage that is initialized with zero at the first call to the method. The caller should not modify the value.

dwEncoding [in]

The code page identifier value for the destination multibyte string. This value is equivalent to the uiCodePage member of the MIMECPINFO structure assigned to dwEncoding.

pSrcStr [in]

The address of the Unicode string to be converted.

pcSrcSize [in, out]

The address of the buffer that stores the length of the source string, in character counts. If this is NULL, or if -1 is specified as the length, the API assumes pSrcStr is null-terminated. When conversion is successful, the method returns the number of characters processed to this buffer.

pDstStr [in]

The address of the string buffer where the conversion result ise stored.

pcDstSize [in, out]

The address of the buffer that stores the length of pDstStr, in byte counts. When conversion is successful, the method returns the number of bytes copied to pDstStr to this buffer.

Return value

Returns one of the following values.

Return codeDescription
S_OK

Success.

S_FALSE

The specified conversion is not supported on the system.

E_FAIL

An error occurred.

 

Remarks

Note that the size of the Unicode string to be converted is specified with a character count, while the size of the multibyte string returned is given in bytes.
