SCSI_IOCTL_PROBE_HOST 0x5385. This command should be given a pointer to a 'char' array as its 3rd
argument. That array should be at least sizeof(int) long and have the
length of the array as an 'int' at the beginning of the array! An ASCII
string of no greater than that length containing "information" (or the
name) of SCSI host (i.e. adapter) associated with this file descriptor is
then placed in the given byte array. N.B. A trailing '\0' may need to
be put on the output string if it has been truncated by the input
length. Returns 1 if host is present, 0 if it is not and a negative
value if there is an error.
