#if 0## Utility for manipulating Book Type Field of Physical Format Descriptor# located in lead-in of DVD+RW media. This is 9th version. 2nd version# added initial support for 2nd generation DVD+RW drives. 3rd version# adds support for DVD+R unit settings. 4th version checks if the unit# is of RICOH design and reliably recognizes drive generation. 5th# version adds support for Benq derivatives. 6th version fixes problem# with USB connected units? 7th version adds support for BTC units.# 8th version fixes typos in BTC support, adds support for fraudulent# NEC firmwares and Lite-On based units. 9th version adds support for# LG, Plextor and dual-format and double-layer Benq units. Keep in mind# that booktyping support might appear in certain firmware revisions,# not necessarily all.## The code is in public domain.## See http://www.dvdplusrw.org/resources/bitsettings.html# for further details.#/bin/sh << EOSMODNAME=\`expr "/$0" : '\(.*[^/]\)/*$' : '.*/\(..*\)' : '\(.*\)\..*$'\`case "`uname -s`" inSunOS)	(set -x; g++ -fno-exceptions -O -o \$MODNAME "$0" -lvolmgt) ;;*)	(set -x; g++ -fno-exceptions -O -o \$MODNAME "$0") ;;esacEOSexit#endif#include <stdio.h>#include <stddef.h>#include <stdlib.h>#include <string.h>#include "transport.hxx"#define OPT_MEDIA	0x01#define OPT_UNIT	0x02#define OPT_UNITRW	0x03#define OPT_UNITR	0x04#define OPT_MASK	0x0F#define OPT_INQ		0x10#define INTERNAL_RELOAD	0x20unsigned short profile;const char    *dev;const char *bookname (unsigned char book,char *unknown=NULL){ const char *ret;    switch(book&0xF0)    {	case 0x00:	ret="-ROM";	break;	case 0x10:	ret="-RAM";	break;	case 0x20:	ret="-R";	break;	case 0x30:	ret="-RW";	break;	case 0x90:	ret="+RW";	break;	case 0xA0:	ret="+R";	break;	case 0xE0:	ret="+R DL";	break;	default:	ret=NULL;			if (unknown)	sprintf (unknown,"?%02X",book&0xFF);			break;    }  return ret;}int mediainfo (Scsi_Command &cmd){ unsigned char buf[8],book;  const char *brand;  int err;    cmd[0]=0xAD;	// READ DVD STRUCTURE    cmd[9]=sizeof(buf);    cmd[11]=0;    if ((err=cmd.transport(READ,buf,sizeof(buf))))    {	sperror ("READ DVD STRUCTURE#0",err);	return 1;    }    book=buf[4];    brand=bookname (book);    printf ("Current media Book Type Field is %02xh: ",book);    if (brand)  printf ("DVD%s specification [revision %d]\n",			brand,book&0xF);    else	printf ("unrecognized value\n");  return 0;}int ricoh (Scsi_Command &cmd,int action,int book,int gen=2){ int err,cnt=0;  unsigned char buf[6];  const char *brand;  char unknown [16]="?unknown";    switch (action)    {	case OPT_INQ|OPT_MEDIA:		break;	case OPT_INQ:	case OPT_INQ|OPT_UNIT:		if (gen==1)	goto inq_unitrw;		cmd[0]=0xFA;		cmd[1]=0x10;		cmd[8]=sizeof(buf);		cmd[11]=0;		if (!cmd.transport(READ,buf,sizeof(buf)))		{   brand = bookname (buf[4],unknown),		    printf ("The unit will brand DVD+R media as DVD%s\n",			    brand?brand:unknown),		    cnt++;		}	case OPT_INQ|OPT_UNITRW:	inq_unitrw:		cmd[0]=0xFA;		cmd[1]=0x00;		cmd[8]=sizeof(buf);		cmd[11]=0;		if (!cmd.transport(READ,buf,sizeof(buf)))		{   brand = bookname (buf[4],unknown),		    printf ("The unit will format DVD+RW media as DVD%s\n",			    brand?brand:unknown),		    cnt++;		}		if (cnt==0)		    printf ("Unable to determine unit settings.
