IWMReaderAdvanced4::GetLanguage method (wmsdkidl.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The GetLanguage method retrieves information about a language supported by an output. You must specify an output number and a language index, and this method will supply the RFC1766-compliant language string.

Syntax

HRESULT GetLanguage(
  [in]      DWORD dwOutputNum,
  [in]      WORD  wLanguage,
  [out]     WCHAR *pwszLanguageString,
  [in, out] WORD  *pcchLanguageStringLength
);

Parameters

[in] dwOutputNum

DWORD containing the output number for which you want to identify the language.

[in] wLanguage

WORD containing the language index of the supported language for which you want the details.

[out] pwszLanguageString

Pointer to a wide-character null-terminated string containing the RFC1766-compliant language string. Pass NULL to retrieve the size of the string, which will be returned in pcbLanguageStringLength.

[in, out] pcchLanguageStringLength

Pointer to a WORD containing the size of pwszLanguageString in wide characters. This size includes the terminating null character.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Remarks

When setting the language to use for an output, you must set the value of the g_wszLanguage setting to the language index passed to this method as wLanguage. Do not use the language index assigned by the language list, which will be different.
