WSA_QOS_EUNKOWNPSOBJ
ObjectType is not part of the provider’s supported object vocabulary
WSA_QOS_EUNKOWNPSOBJ—the misspelling is part of the published constant name—means a QOS_OBJECT_HDR.ObjectType value is unknown to the active QoS provider. The bytes may be well framed and the length valid, yet the provider still cannot assign semantics to the object.
Record the exact object type, provider catalog identity, and Windows version. An object defined for the Traffic Control API, a vendor-specific extension, or another generation of the QoS stack may not be accepted by the RSVP service provider. Do not skip the unknown object and continue, because later objects may depend on its policy or reservation semantics. Build the sequence from documented object types for the selected provider and terminate it with the required end marker.
Compatibility data to capture
- Unknown ObjectType and ObjectLength.
- QoS provider GUID or catalog entry.
- Header or SDK version used to build the object.
- Neighboring objects in the same buffer.
