2 *      @(#)dname.c     1.3 - 95/07/31
3 *     
4 *
5 * RTEMS monitor driver names support.
6 *
7 * There are 2 "driver" things the monitor knows about.
8 *
9 *    1. Regular RTEMS drivers.
10 *         This is a table indexed by major device number and
11 *         containing driver entry points only.
12 *
13 *    2. Driver name table.
14 *         A separate table of names for drivers.
15 *         The table converts driver names to a major number
16 *         as index into the driver table and a minor number
17 *         for an argument to driver.
18 *
19 *  Drivers are displayed with 'driver' command.
20 *  Names are displayed with 'dname' command.
