+// token of the process belongs to user account that is a member of the
+// local Administrators group and it is elevated.
+//
+// RETURN VALUE: Returns TRUE if the primary access token of the process
+// belongs to user account that is a member of the local Administrators
+// group and it is elevated. Returns FALSE if the token does not.

+// contains the Win32 error code of the failure.

+// FUNCTION: IsProcessElevated()
+//
+// PURPOSE: The function gets the elevation information of the current
+// process. It dictates whether the process is elevated or not. Token
+// elevation is only available on Windows Vista and newer operating
+// systems, thus IsProcessElevated throws a C++ exception if it is called
+// on systems prior to Windows Vista. It is not appropriate to use this
+// function to determine whether a process is run as administartor.
+//
+// RETURN VALUE: Returns TRUE if the process is elevated. Returns FALSE if
+// it is not.
+//
+// EXCEPTION: If this function fails, it throws a C++ DWORD exception
+// which contains the Win32 error code of the failure. For example, if
+// IsProcessElevated is called on systems prior to Windows Vista, the error
+// code will be ERROR_INVALID_PARAMETER.
+//
+// NOTE: TOKEN_INFORMATION_CLASS provides TokenElevationType to check the
+// elevation type (TokenElevationTypeDefault / TokenElevationTypeLimited /
+// TokenElevationTypeFull) of the process. It is different from
+// TokenElevation in that, when UAC is turned off, elevation type always
+// returns TokenElevationTypeDefault even though the process is elevated
+// (Integrity Level == High). In other words, it is not safe to say if the
+// process is elevated based on elevation type. Instead, we should use
+// TokenElevation.
+//
+// EXAMPLE CALL:
+// try
+// {
+// if (IsProcessElevated())
+// wprintf (L"Process is elevated\n");
+// else
+// wprintf (L"Process is not elevated\n");
