KBUGCHECK_CALLBACK_RECORD structure

Description

The KBUGCHECK_CALLBACK_RECORD structure is an opaque structure that is used by the KeRegisterBugCheckCallback and KeDeregisterBugCheckCallback routines.

Members

`Entry`

`CallbackRoutine`

`Buffer`

`Length`

`Component`

`Checksum`

`State`

The KBUGCHECK_CALLBACK_RECORD structure is used for bookkeeping by the KeRegisterBugCheckReasonCallback and KeDeregisterBugCheckReasonCallback routines.

The structure must be allocated in resident memory, such as nonpaged pool. Use the KeInitializeCallbackRecord routine to initialize the structure before using it.

For more information about how this structure is used, see Writing a Bug Check Callback Routine.
