Members
DUMMYSTRUCTNAME
DUMMYSTRUCTNAME.TransactionTypeValid
A single bit that indicates that the TransactionType member contains valid data.
DUMMYSTRUCTNAME.OperationValid
A single bit that indicates that the Operation member contains valid data.
DUMMYSTRUCTNAME.LevelValid
A single bit that indicates that the Level member contains valid data.
DUMMYSTRUCTNAME.ProcessorContextCorruptValid
A single bit that indicates that the ProcessorContextCorrupt member contains valid data.
DUMMYSTRUCTNAME.UncorrectedValid
A single bit that indicates that the Uncorrected member contains valid data.
DUMMYSTRUCTNAME.PreciseIPValid
A single bit that indicates that the PreciseIP member contains valid data.
DUMMYSTRUCTNAME.RestartableIPValid
A single bit that indicates that the RestartableIP member contains valid data.
DUMMYSTRUCTNAME.OverflowValid
A single bit that indicates that the Overflow member contains valid data.
DUMMYSTRUCTNAME.ReservedValid
Reserved for system use.
DUMMYSTRUCTNAME.TransactionType
The type of transaction that was in progress when the error occurred. Possible values are:
This member contains valid data only if the TransactionTypeValid bit is set.
DUMMYSTRUCTNAME.Operation
The type of cache operation that caused the error. Possible values are:
This member contains valid data only if the OperationValid bit is set.
DUMMYSTRUCTNAME.Level
The level of the cache where the error occurred.
This member contains valid data only if the LevelValid bit is set.
DUMMYSTRUCTNAME.ProcessorContextCorrupt
A single bit that indicates that the processor context might have been corrupted.
This member contains valid data only if the ProcessorContextCorruptValid bit is set.
DUMMYSTRUCTNAME.Uncorrected
A single bit that indicates that the error has not been corrected.
This member contains valid data only if the UncorrectedValid bit is set.
DUMMYSTRUCTNAME.PreciseIP
A single bit that indicates that the instruction pointer that is specified in the InstructionPointer member of the WHEA_XPF_PROCINFO structure that contains this WHEA_XPF_CACHE_CHECK union is directly associated with the error.
This member contains valid data only if the PreciseIPValid bit is set.
DUMMYSTRUCTNAME.RestartableIP
A single bit that indicates that program execution can be restarted reliably at the instruction pointer that is specified in the InstructionPointer member of the WHEA_XPF_PROCINFO union that contains this WHEA_XPF_CACHE_CHECK structure.
This member contains valid data only if the RestartableIPValid bit is set.
DUMMYSTRUCTNAME.Overflow
A single bit that indicates that an error overflow occurred.
This member contains valid data only if the OverflowValid bit is set.
DUMMYSTRUCTNAME.Reserved
Reserved for system use.
XpfCacheCheck
A ULONGLONG representation of the contents of the WHEA_XPF_CACHE_CHECK union.
Remarks
If the CheckInfoId member of a WHEA_XPF_PROCINFO structure contains WHEA_CACHECHECK_GUID, the CheckInfo member of the WHEA_XPF_PROCINFO structure contains a WHEA_XPF_CACHE_CHECK union.
