6.19. driver_status

One driver can potentially control several host adapters. For example Advansys provide one Linux adapter driver that controls all adapters made by that company - if 2 of more Advansys adapters are in 1 machine, then 1 driver controls both. When ('driver_status' & SG_ERR_DRIVER_SENSE) is true the 'sense_buffer' is also output. The 'driver_status' field has the following values whose #defines mimic those which are only visible within the kernel (with the "SG_ERR_" removed from the front of each define). A copy of these defines can be found in sg_err.h (see the utilities section):

The type of driver_status is unsigned short .
