DUMMYSTRUCTNAME.Reserved1

Reserved.

DUMMYSTRUCTNAME.DataLinkProtocolError

A single bit that indicates that a data link protocol error has occurred.

DUMMYSTRUCTNAME.SurpriseDownError

A single bit that indicates that a surprise down error has occurred.

DUMMYSTRUCTNAME.Reserved2

Reserved.

DUMMYSTRUCTNAME.PoisonedTLP

A single bit that indicates that a poisoned transaction layer packet (TLP) has been detected.

DUMMYSTRUCTNAME.FlowControlProtocolError

A single bit that indicates that a flow control protocol error has occurred.

DUMMYSTRUCTNAME.CompletionTimeout

A single bit that indicates that a completion timeout has occurred.

DUMMYSTRUCTNAME.CompleterAbort

A single bit that indicates that a completer abort has occurred.

DUMMYSTRUCTNAME.UnexpectedCompletion

A single bit that indicates that an unexpected completion has occurred.

DUMMYSTRUCTNAME.ReceiverOverflow

A single bit that indicates that the receiver has overflowed.

DUMMYSTRUCTNAME.MalformedTLP

A single bit that indicates that a malformed transaction layer packet (TLP) has been detected.

DUMMYSTRUCTNAME.ECRCError

A single bit that indicates that an end-to-end cyclic redundancy check (ECRC) error has occurred.

DUMMYSTRUCTNAME.UnsupportedRequestError

A single bit that indicates that an unsupported request error has occurred.

DUMMYSTRUCTNAME.AcsViolation

DUMMYSTRUCTNAME.UncorrectableInternalError

DUMMYSTRUCTNAME.MCBlockedTlp

DUMMYSTRUCTNAME.AtomicOpEgressBlocked

DUMMYSTRUCTNAME.TlpPrefixBlocked

DUMMYSTRUCTNAME.Reserved3

AsULONG

A ULONG representation of the contents of the PCI_EXPRESS_UNCORRECTABLE_ERROR_STATUS structure.

Remarks

The PCI_EXPRESS_UNCORRECTABLE_ERROR_STATUS structure is available in Windows Server 2008 and later versions of Windows.

A PCI_EXPRESS_UNCORRECTABLE_ERROR_STATUS structure is contained in the PCI_EXPRESS_AER_CAPABILITY, PCI_EXPRESS_BRIDGE_AER_CAPABILITY, and PCI_EXPRESS_ROOTPORT_AER_CAPABILITY structures.
