/*
* @(#)dname.c 1.3 - 95/07/31
*
*
* RTEMS monitor driver names support.
*
* There are 2 "driver" things the monitor knows about.
*
* 1. Regular RTEMS drivers.
* This is a table indexed by major device number and
* containing driver entry points only.
*
* 2. Driver name table.
* A separate table of names for drivers.
* The table converts driver names to a major number
* as index into the driver table and a minor number
* for an argument to driver.
*
* Drivers are displayed with 'driver' command.
* Names are displayed with 'dname' command.
*
* $Id$
