KBUGCHECK_TRIAGE_DUMP_DATA structure (wdm.h)

The _KBUGCHECK_TRIAGE_DUMP_DATA structure describes dump data used in conjunction with the KBUGCHECK_REASON_CALLBACK_ROUTINE callback routine.

Syntax

typedef struct _KBUGCHECK_TRIAGE_DUMP_DATA {
  PKTRIAGE_DUMP_DATA_ARRAY DataArray;
  ULONG                    Flags;
  ULONG                    MaxVirtMemSize;
  ULONG                    BugCheckCode;
  ULONG_PTR                BugCheckParameter1;
  ULONG_PTR                BugCheckParameter2;
  ULONG_PTR                BugCheckParameter3;
  ULONG_PTR                BugCheckParameter4;
} KBUGCHECK_TRIAGE_DUMP_DATA, *PKBUGCHECK_TRIAGE_DUMP_DATA;

Members

DataArray

A pointer to a _KBUGCHECK_TRIAGE_DUMP_DATA structure. This is the method the callback uses to provide the triage block data array that it created.

Flags

Flags which are passed into the callback.

KB_TRIAGE_DUMP_DATA_FLAG_BUGCHECK_ACTIVE 0x00000001

Indicates the callback is invoked during a bugcheck. Currently, this flag is expected to always be set.

MaxVirtMemSize

The maximum virtual memory size in bytes the callback is allowed to add to the dump. The cumulative size of the regions described in the data array should not exceed this size.

BugCheckCode

This value informs the callback which bugcheck code that was passed to KeBugcheckEx. The callback routine can use this information to decide whether to add any memory to the crash dump file. For a full list of bug check codes, see the Bugcodes.h header file included in the WDK.

BugCheckParameter1

Bug Check Parameter 1. The bug check parameters inform the callback the bugcheck parameters that were passed to KeBugcheckEx.

BugCheckParameter2

Bug Check Parameter 2. The bug check parameters inform the callback the bugcheck parameters that were passed to KeBugcheckEx.

BugCheckParameter3

Bug Check Parameter 3. The bug check parameters inform the callback the bugcheck parameters that were passed to KeBugcheckEx.

BugCheckParameter4

Bug Check Parameter 4. The bug check parameters inform the callback the bugcheck parameters that were passed to KeBugcheckEx.

Remarks

The driver receives a structure of this type as a parameter to its KBUGCHECK_REASON_CALLBACK_ROUTINE callback routine.

From the callback routine, the driver calls the KeAddTriageDumpDataBlock function to modify a dump data array.
