HRESULT GetLanguageCount(
  DWORD dwOutputNum,
  WORD  *pwLanguageCount
);

Parameters

dwOutputNum

DWORD containing the output number.

pwLanguageCount

Pointer to a WORD containing the language count.

Return value

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

Return code	Description
S_OK	The method succeeded.

Remarks

This method should not be confused with IWMLanguageList::GetLanguageCount. This method retrieves supported languages for a specific output. The methods of the IWMLanguageList interface manipulate a list of languages at the file level. An individual output might not support all of the languages in the language list.
