Clock Driver Major and Minor Number

BSP and Device Driver Development Guide

9.2.1: Major and Minor Number

The major and minor numbers of the clock driver are made available via the following variables.

rtems_device_major_number rtems_clock_major;
rtems_device_minor_number rtems_clock_minor;

The clock device driver is responsible for declaring and initializing these variables. These variables are used by other RTEMS components -- notably the Shared Memory Driver.

NOTE: In a future RTEMS version, these variables may be replaced with the clock device driver registering /dev/clock.
