-.Sh DESCRIPTION
-These functions
-use the SCIOCCOMMAND
-.Xr ioctl 2
-of the FreeBSD SCSI subsystem
-to provide user level access to SCSI commands.
-The programmer must know the SCSI CDB (Command Descriptor
-Block) to perform the desired command.  These functions assist in
-building up the CDB, submitting it to the SCSI subsystem, and decoding
-the result.
-.Pp
-Look at the
-.Xr scsi 8
-command before using the library directly - simple programs are
-best implemented as scripts using that facility.
-.Pp
-To provide for security,
-not all devices accept the SCIOCCOMAND ioctl.  It is accepted by the
-control device for tape drives, partition D for disk drives, partition C
-for CD ROM drives, and any "unknown" device.
-The "super scsi"
-.Xr ssc 4
-device also accepts the ioctl.
-.Pp
-Most of the SCSI library functions build up and manipulate the
-.Fa scsireq
-structure found in the include file
-.Aq Pa sys/scsiio.h :
-.Bd -literal -offset indent
-#define	SENSEBUFLEN 48
-.Pp
-typedef struct	scsireq {
-	u_long	flags;		/* info about the request status and type */
-	u_long	timeout;
-	u_char	cmd[16];	/* 12 is actually the max */
-	u_char	cmdlen;
-	caddr_t	databuf;	/* address in user space of buffer */
-	u_long	datalen;	/* size of user buffer (request) */
-	u_long	datalen_used;	/* size of user buffer (used)*/
-	u_char	sense[SENSEBUFLEN]; /* returned sense will be in here */
-	u_char	senselen;	/* sensedata request size (MAX of SENSEBUFLEN)*/
-	u_char	senselen_used;	/* return value only */
-	u_char	status;		/* what the scsi status was from the adapter */
-	u_char	retsts;		/* the return status for the command */
-	int	error;		/* error bits */
-} scsireq_t;
-.Ed
-.Pp
-.Fn scsireq_new
-allocates a new
-.Fa scsireq
-structure and returns a pointer to it or NULL if it can't allocate
-memory.
-.Pp
-.Fn scsireq_reset
-resets the structure to reasonable values and returns the same pointer passed
-in to it.
-It gracefully handles the NULL pointer passed in to it so that you can
-unconditionally use
-.Fa scsireq_new .
-.Pp
-.Fn scsireq_build
-builds up a scsireq structure based on the information provided in
-the variable argument list.
-It gracefully handles a NULL pointer passed to it.
-.Pp
-.Fa len
-is the length of the data phase; the data transfer direction is
-determined by the
-.Fa flags
-argument.
-.Pp
-.Fa buf
-is the data buffer used during the SCSI data phase.  If it is NULL it
-is allocated via malloc and
-.Fa scsireq->databuf
-is set to point to the newly allocated memory.
-.Pp
-.Fa flags
-are the flags defined in
-.Aq Pa sys/scsiio.h :
-.Bd -literal -offset indent
-/* bit definitions for flags */
-#define SCCMD_READ		0x00000001
-#define SCCMD_WRITE		0x00000002
-#define SCCMD_IOV		0x00000004
-#define SCCMD_ESCAPE		0x00000010
-#define SCCMD_TARGET		0x00000020
-.Ed
-Only two of these flags are supported in this release of the software:
-.Dv SCCMD_READ
-indicates a data in phase (a transfer into the user buffer at
-.Fa scsireg->databuf
-), and
-.Dv SCCMD_WRITE
-indicates a data out phase (a transfer out of the user buffer).
-.Pp
-.Fa fmt
-is a CDB format specifier used to build up the SCSI CDB.
-This text string is made up of a list of field specifiers.  Field
-specifiers specify the value for each CDB field (including indicating
-that the value be taken from the next argument in the
-variable argument list), the width
-of the field in bits or bytes, and an optional name.  White space is
-ignored, and the pound sign ('#') introduces a comment that ends at the
-end of the current line.
-.Pp
-The optional name is the first part of a field specifier and
-is in curly braces.  The text in curly braces in this example are
-the names:
-.Bd -literal -offset indent
-.Fa "{PS} v:b1 {Reserved} 0:b1 {Page Code} v:b6 # Mode select page"
-.Ed
-.Pp
-This field specifier has two one bit fields and one six bit field.
-The second one bit field is the constant value 0 and the first
-one bit field and the six bit field are taken from the variable
-argument list.
-Multi byte fields are swapped into the SCSI byte order in the
-CDB and white space is ignored.
-.Pp
-When the field is a hex value or the letter v, (e.g.,
-.Fa "1A"
-or
-.Fa "v" )
-then a single byte value
-is copied to the next unused byte of the CDB.
-When the letter
-.Fa v
-is used the next integer argument is taken from the variable argument list
-and that value used.
-.Pp
-A constant hex value followed by a field width specifier or the letter
-.Fa v
-followed by a field width specifier (e.g.,
-.Fa 3:4 ,
-.Fa 3:b4 ,
-.Fa 3:i3 ,
-.FR v:i3 )
-specifies a field of a given bit or byte width.
-Either the constant value or (for the V specifier) the next integer value from
-the variable argument list is copied to the next unused
-bits or bytes of the CDB.
-.Pp
-A decimal number or the letter
-.Fa b
-followed by a decimal number field width indicates a bit field of that width.
-The bit fields are packed as tightly as possible beginning with the
-high bit (so that it reads the same as the SCSI spec), and a new byte of
-the CDB is started whenever a byte fills completely or when an
-.Fa i
-field is encountered.
-.Pp
-A field width specifier consisting of the letter
-.Fa i
-followed by either
-1, 2, 3 or 4 indicates a 1, 2, 3 or 4 byte integral value that must
-be swapped into SCSI byte order (MSB first).
-.Pp
-For the
-.Fa v
-field specifier the next integer argument is taken from the variable argument
-list and that value is used swapped into SCSI byte order.
-.Pp
-.Fn scsireq_decode
-is used to decode information from the data in phase of the SCSI
-transfer.
-.Pp
-The decoding is similar to
-the command specifier processing of
-.Fn scsireq_build
-except that the data is extracted from the data pointed to by
-.Fa scsireq->databuf.
-The stdarg list should be pointers to integers instead of integer
-values.
-A seek field type and a suppression modifier are added.
-The
-.Fa *
-suppression modifier (e.g.,
-.Fa *i3
-or
-.Fa *b4 )
-suppresses assignment from the field and can be used to skip
-over bytes or bits in the data, without having to copy
-them to a dummy variable in the arg list.
-.Pp
-The seek field type
-.Fa s
-permits you to skip over data.
-This seeks to an absolute position (
-.Fa s3 )
-or a relative position (
-.Fa s+3 )
-in the data, based on whether or not the presence of the '+' sign.
-The seek value can be specified as
-.Fa v
-and the next integer value from the argument list will be
-used as the seek value.
-.Pp
-.Fn scsireq_buff_decode
-decodes an arbitrary data buffer using the method
-described above in
-.Fn scsireq_decode .
-.Pp
-.Fn scsireq_encode
-encodes the data phase section of the structure.  The encoding is
-handled identically as the encoding of the CDB structure by
-.Fn scsireq_build
-.Pp
-.Fn scsireq_enter
-submits the built up structure for processing using
-the SCIOCCOMMAND ioctl.
-.Pp
-.Fn SCSIREQ_ERROR
-is a macro that determines if the result of the SCIOCCOMMAND ioctl may
-have been
-in error by examining the host adapter return code, whether sense was sent
-or not, and so on.
-.Pp
-.Fn scsi_open
-checks environment variables and initializes the library for
-consistent library use and then calls the regular open system call.
-.Pp
-.Fn scsi_debug
-prints the results of a scsireq_enter function to the specified stdio
-stream.
-.Pp
-.Fn scsi_debug_output
-requests that the results of all transactions be debugged to the
-supplied file using
-.Fn scsi_debug .
-.Sh RETURN VALUES
-The function
-.Fn scsireq_new
-returns a pointer to storage allocated from malloc, and therefore
-potentially a NULL.
-.Pp
-The functions
-.Fn scsireq_build
-and
-.Fn scsireq_reset
-return the same pointer as the one passed in.
-.Pp
-The functions
-.Fn scsireq_buff_decode
-and
-.Fn scsireq_decode
-return the number of assignments performed.
-.Pp
-.Fn scsireq_encode
-returns the number of fields processed.
-.Pp
-The function
-.Fn scsireq_enter
-returns the result of the ioctl call.
-.Sh SEE ALSO
-.Xr scsi 4 ,
-.Xr scsi 8
-.Sh BUGS
-This only works completely for the 1542C.  The host adapter code
-that sets up the residual amount of data transfer has to be added
-to each individual adapter.  This library is usable on the other
-host adapters, however, the SCSI driver pretends that the proper
-amount of data is always transferred.  If you have an Adaptec 174x
-and can hack contact dufault@hda.com and you can have the code to
-calculate residual data for the 174x series to integrate and test.
-.Sh HISTORY
-Many systems have comparable interfaces to permit a user to construct a
-SCSI command in user space.
-.Pp
-The data structure is almost identical to the SGI /dev/scsi data
-structure.  If anyone knows the name of the authors it should
-go here; Peter Dufault first read about it in a 1989 Sun Expert magazine.
-.Pp
-Peter Dufault implemented a clone of SGI's interface in 386bsd that
-led to this library and the related kernel ioctl.
-If anyone needs that for compatibility contact dufault@hda.com.
