class MacSCSIFindDevice
class, SCSI devices Mo, 15. Jul 2002
Mac OS Classic: Works. Mac OS Carbon: does nothing. Windows: does nothing.
Function: Gives information about connected SCSI devices.
Example: See example project.
Notes:
As there is a timeout which is per default 200, you should use the SCSIAvailable check like in the example project.
Inside classic box this class behaves as inside Carbon directly.

AsyncSCSIPresent as integer
property, SCSI devices Sa, 27. Jul 2002
Mac OS Classic: Works. Mac OS Carbon: does nothing. Windows: does nothing.
Function: whether Async SCSI calls can be used.

Bus as integer
property, SCSI devices Mo, 15. Jul 2002
Mac OS Classic: Works. Mac OS Carbon: does nothing. Windows: does nothing.
Function: The number of the current bus.
Example: See example project.
Notes: If there is only one bus, you get 0.

DeviceType as integer
property, SCSI devices Mo, 15. Jul 2002
Mac OS Classic: Works. Mac OS Carbon: does nothing. Windows: does nothing.
Function: The type code for this device.
Notes:
The code is divided into two parts. The lower bit's which you can get using an operation like n=bitwiseand(devicetype,&H1F) are:

kScsiDevTypeDirect0Direct
kScsiDevTypeSequential1Sequential
kScsiDevTypePrinter2Printer
kScsiDevTypeProcessor3
kScsiDevTypeWorm4Write-once, read multiple
kScsiDevTypeCDROM5CD-ROM
kScsiDevTypeScanner6Scanner
kScsiDevTypeOptical7Optical
kScsiDevTypeChanger8Changer
kScsiDevTypeComm9Comm
kScsiDevTypeGraphicArts0A10Graphics Arts
kScsiDevTypeGraphicArts0B11Graphics Arts
kScsiDevTypeFirstReserved12Start of reserved sequence
kScsiDevTypeUnknownOrMissing&h1FUnknown or missing.

Than you have a modifier which you get by n=bitwiseand(devicetype,&E0):

kScsiDevTypeQualifierConnected0,Exists and is connected*/
kScsiDevTypeQualifierNotConnected&h20,Logical unit exists*/
kScsiDevTypeQualifierReserved&h40
kScsiDevTypeQualifierMissing&h60No such logical unit*/
kScsiDevTypeQualifierVendorSpecific&h80Other bits are unspecified

LUN as integer
property, SCSI devices Mo, 15. Jul 2002
Mac OS Classic: Works. Mac OS Carbon: does nothing. Windows: does nothing.
Function: The logical unit number of the current device.
Example: See example project.
Notes: There can be multiple devices with the same ID but different LUNs.

NextDevice as boolean
method, SCSI devices Mo, 15. Jul 2002
Mac OS Classic: Works. Mac OS Carbon: does nothing. Windows: does nothing.
Function: Searches for the next device.
Example: See example project.
Notes: As there is a timeout which is per default 200, you should use the SCSIAvailable check like in the example project.
