PEER_S_NO_EVENT_DATA
Peer event enumeration currently has no more data
PEER_S_NO_EVENT_DATA is HRESULT 6488066 (0x00630002) from winerror.h. AllStat describes it as “There is not more event data.” In the Windows Peer-to-Peer graph, group, event, connection, or subscription state, the value reports a nonfailure state that must not be collapsed into plain S_OK.
Telemetry and tests should retain this result because its operational meaning differs from S_OK.
Where the status is encountered
- Peer Graphing data-store creation and connection; capture the exact API, object, and phase because the same numeric success severity does not define the state by itself.
- Peer group membership and event processing;
- Record subscriptions and offline synchronization;
Keep it attached to the operation that returned it. Interpreting it outside that API contract can turn a normal continuation or partial result into an incorrect retry or false completion.
What must be true before accepting it
Verify that all delivered events were consumed and the caller distinguishes a drained queue from registration failure. That proof prevents usable partial state from being confused with full completion.
Also confirm that returned outputs belong to the current operation generation and were not inherited from an earlier attempt.
Difference from nearby results
This is normal queue exhaustion, whereas PEER_S_NO_CONNECTIVITY describes network reachability.
Precise classification of it selects the correct wait, stop, retry, cleanup, or disclosure path.
Correct handling and recovery
Stop the current read loop and wait for the next event signal or close the registration. Do not busy-poll.
Do not use an unchanged tight retry loop for this HRESULT; it can duplicate effects or conceal a terminal state.
Practical scenario
A peer graph listener drains its event queue and receives this status. It rearms its wait handle instead of treating it as disconnect.
