HS(4) Kernel Interfaces Manual HS(4)NAME
hs - RH11/RS03-RS04 fixed-head disk file
DESCRIPTION
The files hs0 ... hs7 refer to RJS03 disk drives 0 through 7. The files hs8 ... hs15 refer to RJS04 disk drives 0 through 7. The RJS03
drives are each 1024 blocks long and the RJS04 drives are 2048 blocks long.
The hs files access the disk via the system's normal buffering mechanism and may be read and written without regard to physical disk
records. There is also a `raw' inteface which provides for direct transmission between the disk and the user's read or write buffer. A
single read or write call results in exactly one I/O operation and therefore raw I/O is considerably more efficient when many words are
transmitted. The names of the raw HS files begin with rhs. The same minor device considerations hold for the raw interface as for the
normal interface.
In raw I/O the buffer must begin on a word boundary, and counts should be a multiple of 512 bytes (a disk block). Likewise lseek calls
should specify a multiple of 512 bytes.
FILES
/dev/hs?, /dev/rhs?

RK(4) Kernel Interfaces Manual RK(4)NAME
rk - RK-11/RK03 or RK05 disk
DESCRIPTION
Rk? refers to an entire disk as a single sequentially-addressed file. Its 256-word blocks are numbered 0 to 4871. Minor device numbers
are drive numbers on one controller.
The rk files discussed above access the disk via the system's normal buffering mechanism and may be read and written without regard to
physical disk records. There is also a `raw' interface which provides for direct transmission between the disk and the user's read or
write buffer. A single read or write call results in exactly one I/O operation and therefore raw I/O is considerably more efficient when
many words are transmitted. The names of the raw RK files begin with rrk and end with a number which selects the same disk as the corre-
sponding rk file.
In raw I/O the buffer must begin on a word boundary, and counts should be a multiple of 512 bytes (a disk block). Likewise seek calls
should specify a multiple of 512 bytes.
FILES
/dev/rk?, /dev/rrk?
BUGS
In raw I/O read and write(2) truncate file offsets to 512-byte block boundaries, and write scribbles on the tail of incomplete blocks.
Thus, in programs that are likely to access raw devices, read, write and lseek(2) should always deal in 512-byte multiples.
