-typedef struct Disk {
-	char *prefix;

-	int c, h, s;

-Disk* opendisk(char *file, int rdonly, int noctl)
-.SH DESCRIPTION
-These routines provide a simple way to gather
-and use information about 
-disks and disk partitions,
-as well as plain files.
-.PP
-.I Opendisk
-opens
-.I file
-for reading and stores the file descriptor in
-the 
-.B fd
-field of the
-.B Disk
-structure.
-If 
-.I rdonly
-is not set, 
-.I opendisk
-also opens
-.I file
-for writing and stores that file descriptor in
-.BR wfd .
-The two file descriptors are kept separate to
-help prevent accidents.
-.PP
-If
-.I noctl
-is not set, 
-.I opendisk
-looks for a
-.B ctl
-file in the same directory as the
-disk file;
-if it finds one, it declares
-the disk to be
-an
-.I sd
-device,
-setting the
-.B type
-field in the
-.B Disk
-structure
-to
-.BR Tsd .
-If the passed
-.I file
-is named
-.BI fd n disk \fR,
-it looks for a file
-.BI fd n ctl \fR,
-and if it finds that,
-declares the disk to be
-a floppy disk, of type
-.BR Tfloppy .
-If either
-control
-file is found, it is opened for reading
-and writing, and the resulting file descriptor
-is saved as 
-.BR ctlfd .
-Otherwise the returned disk
-has type
-.BR Tfile .
-.PP
-.I Opendisk
-then stats the file and stores its length in
-.BR size .
-If the disk is an
-.I sd
-partition, 
-.I opendisk
-reads the sector size from the
-control
-file and stores it in 
-.BR secsize ;
-otherwise the sector size is assumed to be 512,
-as is the case for floppy disks.
-.I Opendisk
-then stores the disk size measured in sectors in
-.BR secs .
-.PP
-If the disk is an
-.I sd
-partition, 
-.I opendisk 
-parses the
-control
-file to find the partition's offset
-within its disk;
-otherwise it sets
-.B offset
-to zero.
-If the disk is an ATA disk,
-.I opendisk
-reads
-the disk geometry (number of cylinders, heads, and sectors)
-from the 
-.B geometry
-line in the
-.I sd
-control file;
-otherwise it sets these to zero as well.
-.B Name
-is initialized with the base name of
-the disk partition, and is useful for forming messages to the
-.I sd
-control file.
-.B Prefix
-is set to the passed filename without
-the 
-.B name
-suffix.
-.PP
-The IBM PC BIOS interface allocates
-10 bits for the number of cylinders, 8 for 
-the number of heads, and 6 for the number of sectors per track.
-Disk geometries are not quite so simple
-anymore, but to keep the interface useful,
-modern disks and BIOSes present geometries
-that still fit within these constraints.
-These numbers are still used when partitioning
-and formatting disks.
-.I Opendisk
-employs a number of heuristics to discover this
-supposed geometry and store it in the
-.BR c ,
-.BR h ,
-and
-.B s
-fields.
-Disk offsets in partition tables and
-in FAT descriptors are stored in a form
-dependent upon these numbers, so
-.I opendisk
-works hard to report numbers that
-agree with those used by other operating
-systems; the numbers bear little or no resemblance
-to reality.

-.SH BUGS
-Disks on Unix systems do not present the interface
-that 
-.I opendisk
-expects, so
-.I opendisk
-will give them type
-.BR Tfile .

-.SH DESCRIPTION
-These routines provide an interface
-to a SCSI or ATAPI device via Plan 9's
-\fIsd\fR(3).
-.PP
-.I Openscsi
-attempts to open the file
-.IB devdir /raw
-and use it to send raw SCSI commands.
-On success, it reads the device's inquiry
-string and stores it in in returned
-.B Scsi
-structure.
-.I Closescsi
-closes the connection and frees the
-.B Scsi
-structure.
-.PP
-.I Scsiready
-sends the ``unit ready'' command up to three times,
-returning zero if the unit responds that it is ready,
-or \-1 on error.
-.PP
-.I Scsierror
-returns a textual description of the SCSI status
-denoted by the ASC and ASCQ sense codes.
-The description is found by consulting
-.BR /sys/lib/scsicodes .
-The returned string will be overwritten by
-the next call to
-.IR scsierror .
-.PP
-.I Scsi
-and
-.I scsicmd
-execute a single SCSI command on the named device.
-There should be 
-.I ncmd
-bytes of
-command data in 
-.IR cmd ;
-if
-.I dir
-is 
-.BR Sread ,
-a successful operation
-will store up to
-.I ndata
-bytes into
-.IR data ,
-returning the number of bytes stored.
-If
-.I dir
-is
-.BR Swrite ,
-the 
-.I ndata
-bytes beginning at
-.I data
-are transmitted as the data argument to
-the command, and the
-number of bytes written is returned.
-If
-.I dir
-is
-.BR Snone ,
-.I data
-and
-.I ndata
-are ignored.
-On error, 
-.I scsi
-and
-.I scsicmd
-return \-1.
-.I Scsicmd
-simply issues the command and
-returns the result;
-.I scsi
-works a bit harder and
-is the more commonly used routine.
-.I Scsi
-attempts to send the command;
-if it is successful, 
-.I scsi
-returns what
-.I scsicmd
-returned.
-Otherwise, 
-.I scsi
-sends a request sense command to
-obtain the reason for the failure,
-sends a unit ready command in
-an attempt to bring the unit out of any
-inconsistent states, and tries again.
-If the second try fails,
-.I scsi 
-sends the request
-sense and unit ready commands
-again
-and then uses
-.I scsierror
-to set
-.I errstr
-with a reason for failure.
-.PP
-The 
-.B nchange
-and
-.B changetime
-fields
-in the
-.B Scsi
-structure
-record the number of times a media
-change has been detected, and the
-time when the current media was
-inserted into the drive (really the
-first time a SCSI command was issued
-after it was inserted).
-They are maintained by 
-.IR scsi .
-.PP
-If
-.I scsiverbose
-is set,
-these commands will produce a fair
-amount of debugging output on file descriptor 2
-when SCSI commands fail.
