+/* * This program reads various mode pages and bits of other
+ * information from a scsi device and interprets the raw data for you
+ * with a report written to stdout. Usage:
+ *
+ * ./sginfo [options] /dev/sg2 [replace parameters]
+ *
+ * Options are:
+ * -6 do 6 byte mode sense + select (default: 10 byte)
+ * -a display all mode pages reported by the device: equivalent to '-t 63'.
+ * -A display all mode pages and subpages reported by the device: equivalent
+ * to '-t 63,255'.
+ * -c access Cache control page.
+ * -C access Control Page.
+ * -d display defect lists (default format: index).
+ * -D access disconnect-reconnect page.
+ * -e access Read-Write error recovery page.
+ * -E access Control Extension page.
+ * -f access Format Device Page.
+ * -Farg defect list format (-Flogical, -flba64, -Fphysical, -Findex, -Fhead)
+ * -g access rigid disk geometry page.
+ * -G display only "grown" defect list (default format: index)
+ * -i display information from Inquiry command.
+ * -I access Informational Exceptions page.
+ * -l list known scsi devices on the system [deprecated]
+ * -n access notch parameters page.
+ * -N Negate (stop) storing to saved page (active with -R)
+ * -P access Power Condition Page.
+ * -r list known raw scsi devices on the system
+ * -s display serial number (from INQUIRY VPD page)
+ * -t <n[,spn]> access page number <n> [and subpage <spn>], try to decode
+ * -u <n[,spn]> access page number <n> [and subpage <spn>], output in hex
+ * -v show this program's version number
+ * -V access Verify Error Recovery Page.
+ * -T trace commands (for debugging, double for more debug)
+ * -z do a single fetch for mode pages (rather than double fetch)
+ *
+ * Only one of the following three options can be specified.
+ * None of these three implies the current values are returned.
+ * -m Display modifiable fields instead of current values
+ * -M Display manufacturer defaults instead of current values
+ * -S Display saved defaults instead of current values
+ *
+ * -X Display output values in a list.
+ * -R Replace parameters - best used with -X
+ *

+ *
+ * Kurt Garloff
+ * 20000715 allow displaying and modification of vendor specific pages
+ * (unformatted - @ hexdatafield)
+ * accept vendor lengths for those pages
+ * enabled page saving
+ * cleaned parameter parsing a bit (it's still a terrible mess!)
+ * Use sr (instead of scd) and sg%d (instead of sga,b,...) in -l
+ * and support much more devs in -l (incl. nosst)
+ * Fix segfault in defect list (len=0xffff) and adapt formatting
+ * to large disks. Support up to 256kB defect lists with
+ * 0xB7 (12byte) command if necessary and fallback to 0x37
+ * (10byte) in case of failure. Report truncation.
+ * sizeof(buffer) (which is sizeof(char*) == 4 or 32 bit archs)
