; Disk driver to create FAT16/FAT32 memory-based temporary disk aka RAM disk.
|
||||
; (c) CleverMouse
|
||||
|
||||
; Note: in the ideal world, a disk driver should not care about a file system
|
||||
; on it. In the current world, however, there is no way to format a disk in
|
||||
; FAT, so this part of file-system-specific operations is included in the
|
||||
; driver.
|
||||
|
||||
; When this driver is loading, it registers itself in the system and does
|
||||
; nothing more. When loaded, this driver controls pseudo-disk devices
|
||||
; named /tmp#/, where # is a digit from 0 to 9. The driver does not create
|
||||
; any device by itself, waiting for instructions from an application.
|
||||
; The driver responds to the following IOCTLs from a control application:
|
||||
SRV_GETVERSION equ 0 ; input ignored,
|
||||
; output = dword API_VERSION
|
||||
DEV_ADD_DISK equ 1 ; input = structure add_disk_struc,
|
||||
; no output
|
||||
DEV_DEL_DISK equ 2 ; input = structure del_disk_struc,
|
||||
; no output
|
||||
; For all IOCTLs the driver returns one of the following error codes:
|
||||
NO_ERROR equ 0
|
||||
ERROR_INVALID_IOCTL equ 1 ; unknown IOCTL code, wrong input/output size...
|
||||
ERROR_INVALID_ID equ 2 ; .DiskId must be from 0 to 9
|
||||
ERROR_SIZE_TOO_LARGE equ 3 ; .DiskSize is too large
|
||||
