;This is the assembly language INCLUDE file for the FileIO requester 1.9

; The file IO which is returned by GetFileIO() looks like this
;
;	The FileIO structure (264 bytes):
;FileIO	dc.w  0      ;Flags WORD
;			ds.b  30     ;FileName buffer (contents must be NULL terminated)
;			ds.b  132    ;DrawerName buffer
;			ds.b  30     ;DiskName buffer
;			dc.l   0     ;DOS filehandle lock
;			dc.w   0     ;NameCount (total # of filenames in filename list)
;			dc.w   0     ;NameStart (ID of filename in top "select name" display)
;			dc.w   0     ;CurrentPick (ID of filename selected and highlighted)
;			dc.l NameKey ;address of Remember structure for filename list
;			dc.l   0     ;NextDisk Text (for SPECIAL_REQ)
;			dc.l   0     ;address of NextDisk handler (for SPECIAL_REQ)
;the next 2 fields are for WB pattern match (i.e. Icon files displayed only)
;			dc.w   0     ;DiskObjectType to match
;			dc.l   0     ;ToolTypes string address to match
;			dc.l   0     ;address of extension string to match
;			dc.w   0     ;size of extension string
;			dc.l   0     ;address of CustomHandler structure
;			dc.w   0     ;X position of the requester
;			dc.w   0     ;Y position of the requester
;			dc.l   0     ;free bytes on current disk
;			dc.l   0     ;bytesize of selected file (or 0 if the file doesn't exist yet)
;			dc.l   0     ;WindowTitle
;			dc.l   0     ;Buffer
;			dc.l   0     ;Rawkey Code
;			dc.l   0     ;OriginalLock (do not alter)
;			dc.b   0     ;Error number
;			dc.b   0     ;DrawMode
;			dc.b   0     ;PenA
;			dc.b   0     ;PenB

; so here are the offsets from the base for each field:

FILEIO_FLAGS		equ 0
FILEIO_FILENAME	equ 2
FILEIO_DRAWER		equ 32
FILEIO_DISK			equ 164
FILEIO_LOCK			equ 194
FILEIO_NAMECOUNT	equ 198
FILEIO_NAMESTART	equ 200
FILEIO_CURRPICK	equ 202
FILEIO_FILELIST	equ 204
FILEIO_TEXT			equ 208
FILEIO_ROUTINE		equ 212
FILEIO_MATCHTYPE	equ 216
FILEIO_TOOLTYPES	equ 218
FILEIO_EXTENSION	equ 222
FILEIO_EXTSIZE		equ 226
FILEIO_CUSTOM		equ 228
FILEIO_X				equ 232
FILEIO_Y				equ 234
FILEIO_FREEBYTES	equ 236
FILEIO_FILESIZE	equ 240
FILEIO_TITLE		equ 244
FILEIO_BUFFER		equ 248
FILEIO_RAWCODE		equ 252
FILEIO_ORIGINALLOCK	equ 256
FILEIO_ERRNO		equ 260
FILEIO_DRAWMODE	equ 261
FILEIO_PENA			equ 262
FILEIO_PENB			equ 263

SIZEOF_FILEIO		equ 264

;  So, to access the FileIO's Tooltypes field, you can do this
;
;move.l  myFileIO,a0             ;the base returned from GetFileIO()
;move.l  FILEIO_TOOLTYPES(a0),d0 ;get the value in this field

; Here the the flag bit numbers

NO_CARE_REDRAW		equ 0
USE_DEVICE_NAMES	equ 1
EXTENSION_MATCH	equ 2
DOUBLECLICK_OFF	equ 3
WBENCH_MATCH		equ 4
MATCH_OBJECTTYPE	equ 5
MULTIPLE_FILES		equ 6
INFO_SUPPRESS		equ 7

ALLOCATED_FILEIO	equ 8		;NEVER alter this
CUSTOM_HANDLERS	equ 9
WINDOW_OPENED		equ 10	;NEVER alter this
TITLE_CHANGED		equ 11
NO_ALPHA				equ 12
DISK_HAS_CHANGED	equ 13
SHOW_DISK_NAMES	equ 14	;for displaying disk instead of file names
SPECIAL_REQ			equ 15	;for displaying lists of strings

; So to enable the USE_DEVICE_NAMES feature, do this
;
;movea.l  myFileIO,a0           ;the base
;move.w   FILEIO_FLAGS(a0),d0   ;get the current flags
;bset.l   #USE_DEVICE_NAMES,d0  ;enable this feature (clear the bit to disable)
;move.w   d0,FILEIO_FLAGS(a0)   ;save the new flags
 
 ;======= ERRNO numbers returned in FileIO error field =========

ERR_MANUAL  equ 1   ;the path was entered manually via the title bar with no
                    ;errors or cancellation.
ERR_SUCCESS equ 0   ;everything went OK in DoFileIO() or DoFileIOWindow()
ERR_CANCEL  equ -1  ;the filename procedure was CANCELED by the user
ERR_INUSE   equ -2  ;for SPECIAL_REQ, another task is using the requester
ERR_APPGADG equ -3  ;the requester was CANCELED by an application gadget
                    ;(via an installed CUSTOM gadget handler returning TRUE)
ERR_WINDOW  equ -4  ;the window couldn't open (in DoFileIOWindow())

 ;====== AutoFileMessage() numbers =========
ALERT_OUTOFMEM       equ  0
ALERT_BAD_DIRECTORY  equ  1
READ_WRITE_ERROR     equ  2 ; Error in reading or writing file
 ;The next 3 display "YES" and "NO" prompts, returning d0=1 for yes, 0 for no
FILE_EXISTS          equ  3 ; File already exists. Overwrite?
SAVE_CHANGES         equ  4 ; Changes have been made. Save them?
REALLY_QUIT          equ  5 ; Do you really want to quit?
