WSA_QOS_GENERIC_ERROR
A generic result is a signal to recover the provider-specific detail
WSA_QOS_GENERIC_ERROR provides no reliable diagnosis beyond failure in the Winsock QoS path. It can be returned when the provider cannot map an internal condition to one of the structural, policy, admission, or traffic-control codes. Treating it as an ordinary network outage loses the distinction between local API validation and RSVP signaling.
Read any RSVP_STATUS_INFO object supplied with the FD_QOS event, including ExtendedStatus1 and ExtendedStatus2. Record the exact Winsock call, socket state, QOS buffer, and provider catalog entry. Then reproduce with the smallest valid FLOWSPEC before adding provider-specific objects. Because legacy GQOS and RSVP support changed across Windows releases, also record the operating-system version and whether the application is using the older RSVP service provider or the newer QWave API.
Context required to disambiguate the code
- Failing Winsock function or FD_QOS event.
- Full QOS structure and provider-specific bytes.
- ExtendedStatus1 and ExtendedStatus2.
- QoS provider and Windows version.
