hi
i'm not sure if i can use that ioctl, as my program needs to tarnslate
from a file-name into scsi target-id and logical-unit, and the ioctl you
have mentioned can do it with a file-descriptor to an open device, but i
don't have the device name to open.
i saw that stat(2) returns info about the device at the st_dev field.
is it possible to translate from that field to the device name, or is it
possible to open a device using the dev field extracted by stat?
please CC me for any answer as i'm not register to the mailing list
