>The third argument is assumed to point to an int. The default value is 0.

If this call is made pointing to an int greater than 0 then any SCSI
|
|
request that is issued that results in the SCSI status of CHECK_CONDITION
|
|
(or COMMAND_TERMINATED) will cause a message to be sent to the log (and
|
|
perhaps the console). The message is information derived from the sense
|
|
buffer (i.e. the SCSI error message) and it is prefixed with
|
|
"sg_cmd_done_bh".</P
