3669 | =========== Function 68, subfunction 31 - get driver data. =========== |
| - | 3670 | ====================================================================== |
|
| - | 3671 | Driver structures are organized into a doubly linked list. Its head is |
|
| - | 3672 | a dummy structure with the forward and backward pointers only. Other |
|
| - | 3673 | structures, if any, are as follows: |
|
| - | 3674 | * +0: 16*byte: driver name, ASCIIZ |
|
| - | 3675 | * +16 = +0x10: dword: pointer to the next driver structure |
|
| - | 3676 | * +20 = +0x14: dword: pointer to the previous driver structure |
|
| - | 3677 | * +24 = +0x18: dword: driver's base address |
|
| - | 3678 | * +28 = +0x1C: dword: driver's entry point address |
|
| - | 3679 | * +32 = +0x20: dword: driver's service handler address |
