IWMReaderNetworkConfig::GetLoggingUrl method

The GetLoggingUrl method retrieves a URL from the list of servers that receive logging information from the reader object. Use the IWMReaderNetworkConfig::GetLoggingUrl method to add servers to the list.

Syntax


HRESULT GetLoggingUrl(
  [in]      DWORD  dwIndex,
  [out]     LPWSTR pwszUrl,
  [in, out] DWORD  *pcchUrl
);

Parameters

dwIndex [in]

Specifies which URL to retrieve, indexed from zero. To get the number of URLs, call the IWMReaderNetworkConfig::GetLoggingUrlCount method.

pwszUrl [out]

Pointer to a buffer that receives a string containing the URL. The caller must allocate the buffer.

pcchUrl [in, out]

On input, specifies the length of the pwszUrl buffer, in characters. On output, receives the length of the URL, including the terminating null character.

Return value

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

Return codeDescription
S_OK

The method succeeded.

E_INVALIDARG

NULL or invalid argument passed in.

ASF_E_BUFFERTOOSMALL

Size passed in to pcchUrl is too small.

 

Remarks

You should make two calls to GetLoggingUrl. On the first call, pass NULL for pwszUrl. On return, the value pointed to by pcchUrl is set to the number of wide characters, including the terminating null, 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.
