The GetHostURL method retrieves the URL from which the stream is broadcast. Clients will access the stream from this URL.
HRESULT GetHostURL( WCHAR *pwszURL, DWORD *pcchURL );
Pointer to buffer that receives a string containing the URL. To retrieve the length of the string, set this parameter to NULL.
On input, pointer to the size of pwszURL, in characters. On output, this parameter receives the length of the URL in characters, including the terminating null character.
The method returns an HRESULT. Possible values include, but are not limited to, the values shown in the following table.
||The method succeeded.|
||The buffer is too small.|
||Invalid argument; pcchURL cannot be NULL.|
||The network sink is not connected.|
You should make two calls to GetHostURL. On the first call, pass NULL as pwszURL. On return, the value pointed to by pcchURL is set to the number of characters, including the terminating null character, required to hold the URL. Then you can allocate the required amount of memory for the string and pass a pointer to it as pwszURL on the second call.
