SCSIWrite

SCSIWrite Transfer data from the initiator to the target

#include <SCSI.h> SCSI Manager

Ptr tibPtr; pointer to a transfer instruction block

returns 16-bit Error Code; 0=no error

SCSIWrite transfers data from the initiator to the target, as specified by

the transfer instructions block pointed to by tibPtr.

Returns: an error code indicating success or failure of the function. It will be

one of:

noErr (0) No error

scBadParmsErr (4) Unrecognized instruction in transfer instruction block

scCommErr (2) Breakdown in SCSI protocols

scPhaseErr (5) Phase error

Notes: The error codes returned by SCSI Manager routines typically indicate

only that a given operation has failed. To determine the actual cause of the

failure, another SCSI command needs to be sent asking the device what went

wrong.

A transfer instructions block tells the SCSI Manager what to do

with the data bytes transferred during the data phase. A transfer instruction

block contains a pseudo-program consisting of a variable number of

instructions; it's similar to a subroutine except that the instructions are

provided and interpreted by the SCSI Manager itself. The instructions are

of a fixed size and are of type SCSIInstr. See SCSIInstr for more

information on the the instructions that are available.

Use SCSISelect to specify the target device.
