-// Call this function twice to get the name of the named destination:
-// 1) First time pass in |buffer| as NULL and get buflen.
-// 2) Second time pass in allocated |buffer| and buflen to retrieve |buffer|, which should be used as wchar_t*.
-// If buflen is not sufficiently large, it will be set to -1 upon return.
