6.15. masked_status

Logically: masked_status == ((status & 0x3e) >> 1) . So 'masked_status' strips the vendor information bits off 'status' and then shifts it right one position. This makes it easier to do things like "if (CHECK_CONDITION == masked_status) ..." using the definitions in <scsi/scsi.h>. The defined values in this file are:

• GOOD [0x00]

• CHECK_CONDITION [0x01]

• CONDITION_GOOD [0x02]

• BUSY 0x04

• INTERMEDIATE_GOOD 0x08

• INTERMEDIATE_C_GOOD 0x0a

• RESERVATION_CONFLICT 0x0c

• COMMAND_TERMINATED 0x11

• QUEUE_FULL 0x14

N.B. 1 bit offset from usual SCSI status values

Note that SCSI 3 defines some additional status codes. The type of masked_status is unsigned char .
