pwszUrl [out]

Return codeDescription

The method succeeded.


NULL or invalid argument passed in.


Size passed in to pcchUrl is too small.



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.
