* \file unallocated_resource_win_invalid_handle_value.cpp
* \author Andrey Semashev
*
* \brief This file tests that \c unallocated_resource supports
* \c INVALID_HANDLE_VALUE on Windows, as is described in the docs.
*
* This code relies on MSVC-specific behavior, which allows* \c INVALID_HANDLE_VALUE
* to be specified in non-type template parameters.
