The D3DDDI_QUERYREGISTRY_STATUS enumeration contains retrieved status codes via a QueryAdapterInfo call for KMTQAITYPE_QUERYREGISTRY.
D3DDDI_QUERYREGISTRY_STATUS_SUCCESSIndicates full success, and QueryAdapterInfo succeeded as well. All D3DDDI_QUERYREGISTRY_INFO fields starting with Output*Xxx* and the D3DDDI_QUERYREGISTRY_INFO::Status field are updated by QueryAdapterInfo.
D3DDDI_QUERYREGISTRY_STATUS_BUFFER_OVERFLOWD3DKMT_QUERYADAPTERINFO::PrivateDriverDataSize wasn't large enough to retrieve all the requested data. Only D3DDDI_QUERYREGISTRY_INFO\::OutputValueSize is updated by QueryAdapterInfo, in addition to the D3DDDI_QUERYREGISTRY_INFO::Status field.
D3DDDI_QUERYREGISTRY_STATUS_FAILAn unspecified error occurred, and QueryAdapterInfo failed as well. All other D3DDDI_QUERYREGISTRY_INFO fields are left unmodified upon return from QueryAdapterInfo. Since D3DDDI_QUERYREGISTRY_INFO is a variable-sized struct, D3DDDI_QUERYREGISTRY_STATUS_FAIL will reliably occur when D3DKMT_QUERYADAPTERINFO::PrivateDriverDataSize is smaller than the size of D3DDDI_QUERYREGISTRY_INFO.
D3DDDI_QUERYREGISTRY_STATUS_MAXD3DDDI_QUERYREGISTRY_STATUS_MAX is invalid to use, and exists only to simplify maintaining the implementation.
