DRIVER_OBJECT结构

DRIVER_OBJECT STRUCT ; sizeof= 0A8h

_Type SWORD ? ; 0000h (IO_TYPE_DRIVER = 4) (original field name Type)

_Size SWORD ? ; 0004h (original name Size)

; The following links all of the devices created by a single driver

; together on a list, and the Flags word provides an extensible flag

; location for driver objects.

DeviceObject PVOID ? ; 0004h PTR DEVICE_OBJECT

Flags DWORD ? ; 0008h

; The following section describes where the driver is loaded. The count

; field is used to count the number of times the driver has had its

; registered reinitialization routine invoked.

DriverStart PVOID ? ; 000Ch

DriverSize DWORD ? ; 0010h

DriverSection PVOID ? ; 0014h

DriverExtension PVOID ? ; 0018h PTR DRIVER_EXTENSION

; The driver name field is used by the error log thread

; determine the name of the driver that an I/O request is/was bound.

DriverName UNICODE_STRING <> ; 001Ch

; The following section is for registry support. Thise is a pointer

; to the path to the hardware information in the registry

HardwareDatabase PVOID ? ; 0024h PTR UNICODE_STRING

; The following section contains the optional pointer to an array of

; alternate entry points to a driver for "fast I/O" support. Fast I/O

; is performed by invoking the driver routine directly with separate

; parameters, rather than using the standard IRP call mechanism. Note

; that these functions may only be used for synchronous I/O, and when

; the file is cached.

FastIoDispatch PVOID ? ; 0028h PTR FAST_IO_DISPATCH

; The following section describes the entry points to this particular

; driver. Note that the major function dispatch table must be the last

; field in the object so that it remains extensible.

DriverInit PVOID ? ; 002Ch

DriverStartIo PVOID ? ; 0030h

DriverUnload PVOID ? ; 0034h

MajorFunction PVOID (IRP_MJ_MAXIMUM_FUNCTION + 1) dup(?) ; 0038h
