Subject: [PATCH v2 2/8] net/ring: build on Windows
Date: Mon,  6 Feb 2023 16:19:31 -0800	[thread overview]
Message-ID: <20230207001937.875608-3-stephen@networkplumber.org> (raw)
In-Reply-To: <20230207001937.875608-1-stephen@networkplumber.org>

The command line arguments are stored in node_action_pair
and the name[] was sized to PATH_MAX which does not exist on Windows.
Since the name is either "CREATE" or "ATTACH" it is not
related to PATH_MAX (4096).

With this fix driver builds ok on windows, but need to modify the
test meson build to skip the eventdev test on Windows.
