Section 4: Device Descriptions

This section of the manual describes the Xinu device drivers available on the distribution tape.  Each device driver implements the device independent I/O routines open, close, read, write, seek, getc, putc, control, and init, for one physical or pseudo-device.  While the intuitive meanings of these routines are the same across all devices, each driver defines specific, sometimes device dependent meaning to them.  If a particular operation does not make sense for a given device, the driver may choose to return SYSERR or OK without taking further action.
