| /* NOTICE: |
| * On 5th October 2004 (v1.00) this file name was changed from sg_err.c |
| * to sg_lib.c and the previous GPL was changed to a FreeBSD license. |
| * The intention is to maintain this file and the related sg_lib.h file |
| * as open source and encourage their unencumbered use. |
| * |
| * CONTRIBUTIONS: |
| * This file started out as a copy of SCSI opcodes, sense keys and |
| * additional sense codes (ASC/ASCQ) kept in the Linux SCSI subsystem |
| * in the kernel source file: drivers/scsi/constant.c . That file |
| * bore this notice: "Copyright (C) 1993, 1994, 1995 Eric Youngdale" |
| * and a GPL notice. |
| * |
| * Much of the data in this file is derived from SCSI draft standards |
| * found at http://www.t10.org with the "SCSI Primary Commands-4" (SPC-4) |
| * being the central point of reference. |
| * |
| * Other contributions: |
| * Version 0.91 (20031116) |
| * sense key specific field (bytes 15-17) decoding [Trent Piepho] |
| * |
| * CHANGELOG (changes prior to v0.97 removed): |
| * v0.97 (20040830) |
| * safe_strerror(), rename sg_decode_sense() to sg_normalize_sense() |
| * decode descriptor sense data format in full |
| * v0.98 (20040924) [SPC-3 rev 21] |
| * renamed from sg_err.c to sg_lib.c |
| * factor out sg_get_num() and sg_get_llnum() into this file |
| * add 'no_ascii<0' variant to dStrHex for ASCII-hex output only |
| * v1.00 (20041012) |
| * renamed from sg_err.c to sg_lib.c |
| * change GPL to FreeBSD license |
