rtems_semaphore routines on SMP systems

[Andrew.Butterfield at scss.tcd.ie]

Yes,
  if you #define RTEMS_SMP you can use the MrsP protocol (for example) by calling
 rtems_semaphore_create with an attribute set containing 
RTEMS_PRIORITY  | RTEMS_BINARY_SEMAPHORE  | RTEMS_MULTIPROCESSOR_RESOURCE_SHARING.

You can then use rtems_semaphore_obtain, rtems_semaphore_release
, rtems_semaphore_delete and others in the usual way.

Best Regards,
 Andrew Butterfield

    Can the rtems_semaphore_*() routines be used on SMP systems?
