/* ntp_clockdev.h - map clock instances to devices
 *
 * Written by Juergen Perlinger (perlinger (at) ntp.org) for the NTP project.
 * The contents of 'html/copyright.html' apply.
 * ---------------------------------------------------------------------
 * The runtime support for the 'device' configuration statement.  Just a
 * simple list to map refclock source addresses to the device(s) to use
 * instead of the builtin names.
