9 * \file unallocated_resource_win_invalid_handle_value.cpp
10 * \author Andrey Semashev
11 *
12 * \brief This file tests that \c unallocated_resource supports
13 * \c INVALID_HANDLE_VALUE on Windows, as is described in the docs.
14 *
15 * This code relies on MSVC-specific behavior, which allows* \c INVALID_HANDLE_VALUE
16 * to be specified in non-type template parameters.
