Subject: [PATCH v3 23/30] selftests: ntsync: Add some tests for manual-reset event state.
Date: Thu, 28 Mar 2024 19:06:14 -0500 [thread overview]
Message-ID: <20240329000621.148791-24-zfigura@codeweavers.com> (raw)
In-Reply-To: <20240329000621.148791-1-zfigura@codeweavers.com>
Test event-specific ioctls NTSYNC_IOC_EVENT_SET, NTSYNC_IOC_EVENT_RESET,
NTSYNC_IOC_EVENT_PULSE, NTSYNC_IOC_EVENT_READ for manual-reset events, and
waiting on manual-reset events.
