DUMMYSTRUCTNAME.MultipleCorrectableErrorsReceived
A single bit that indicates that multiple correctable error messages have been received.
DUMMYSTRUCTNAME.UncorrectableErrorReceived
A single bit that indicates that an uncorrectable error message has been received.
DUMMYSTRUCTNAME.MultipleUncorrectableErrorsReceived
A single bit that indicates that multiple uncorrectable error messages have been received.
DUMMYSTRUCTNAME.FirstUncorrectableFatal
A single bit that indicates that the first uncorrectable error message that was received was for a fatal error.
DUMMYSTRUCTNAME.NonFatalErrorMessagesReceived
A single bit that indicates that one or more non-fatal uncorrectable error messages have been received.
DUMMYSTRUCTNAME.FatalErrorMessagesReceived
A single bit that indicates that one or more non-fatal uncorrectable error messages have been received.
DUMMYSTRUCTNAME.Reserved
Reserved.
DUMMYSTRUCTNAME.AdvancedErrorInterruptMessageNumber
The MSI/MSI-X vector that is used for the interrupt messages that are generated in association with any of the status bits of the advanced error reporting capability.
AsULONG
A ULONG representation of the contents of the PCI_EXPRESS_ROOT_ERROR_STATUS structure.
Remarks
