- 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.
