Process a disk insert event that caused an error

#include <DiskInit.h> Disk Initialization Package

short DIBadMount( globalPt, evtMessage );

Point globalPt ; top-left corner of DI dialog (global coordinates)

long evtMessage ; message field of a EventRecord

returns an Error Code; 0=no error

You can call DIBadMount when a call to GetNextEvent returns a diskEvt

event and the returned message indicates an error (the high word is

non-zero). It draws a dialog and (if the user OKs it) formats the disk and sets

up an empty directory, block map, and volume information.

globalPt is a Point, expressed in global ( screen) coordinates. It identifies

where you want to put the top left corner of the "Do you want to

evtMessage is a 32-bit code. The low word identifies the drive on which you

want to format a disk. The high word is an OSErr code as returned

from PBMountVol (e.g., ioErr, noMacDskErr, etc.).

This parameter matches the message field of an EventRecord

returned by GetNextEvent when the what field has been set to

Returns: an integer result code. Negative values are OSErr codes. It will be

Notes: By the time you get a diskEvt back from GetNextEvent, the Event

Manager has already attempted to mount the volume. If you are using the

lower-level GetOSEvent, then you should attempt to mount it using

PBMountVol and check for an error before calling DIBadMount.

Most applications can simply ignore disk insertions. If you use Standard

File to get filenames, that package will take care of disk insertions,

ejections, and formatting. If you'd rather do it yourself, you can use the

Point diDlgPt;

short rc;

GetNextEvent( everyEvent, & theEvent)

if ( theEvent.what == diskEvt ) {

if (( theEvent.message & 0xFFFF0000) != 0) {/*err mounting*/

SetPt( &diDlgPt, 100,100 );

rc = DIBadMount( diDlgPt, theEvent. message); /* do it */

if ( rc < 0 ) { ... some error occurred ... }

}
