   BOOL LoadUserProfile(
     HANDLE hToken,
     LPPROFILEINFO lpProfileInfo
   );

   hToken is a token for the user. The token must have TOKEN_IMPERSONATE
   access.

   lpProfileInfo is a pointer to a PROFILEINFO structure.
				

   BOOL UnloadUserProfile(
     HANDLE hToken,

   );
				

   BOOL GetUserProfileDirectory(
     HANDLE  hToken,
     LPTSTR lpProfileDir,
