This directory contains include files that describe device-specific
characteristics of Sprite I/O devices. Typically, each file describes
the Fs_IOControl operations implemented by that device, and any
structures passed to or from the device handler via Fs_IOControls.
Generic Fs_IOControl operations (those that are implemented for
many or all device and file types) are described in
/sprite/lib/include/fs.h.
Corresponding to each I/O device is an index, which appears in the
high-order 16 bits of the operation code for each Fs_IOControl for
that device. The current indices are listed below. Add new ones when
you define new kinds of devices.
generic operations (fs.h) 0
terminals (tty.h) 1
pseudo-devices (pdev.h) 2
magnetic tapes (tape.h) 3
network protocols (net.h) 4
write-once optical disks (worm.h) 5
pseudo-file-systems (pfs.h) 6
graphics devices (graphics.h) 7
