subttl "Macro to dispatch exception"
|
|
|
|
;++

|

|
|
; Macro Description:
|
|
;
|
|
; This macro allocates exception record on stack, sets up exception
|
|
; record using specified parameters and finally sets up arguments
|
|
; and calls _KiDispatchException.
|
|
;
|
|
; Arguments:
|
|
;
|
|
; ExcepCode - Exception code to put into exception record
|
|
; ExceptFlags - Exception flags to put into exception record
|
|
; ExceptRecord - Associated exception record
|
|
; ExceptAddress - Addr of instruction which the hardware exception occurs
|
|
; NumParms - Number of additional parameters
|
|
; ParameterList - the additional parameter list
|
|
;
|
|
; Return Value:
|
|
;
|
|
; None.
