  • score/Makefile.am, score/include/rtems/score/thread.h: Added sync() service. As part of adding this service, the new RTEMS service rtems_iterate_over_all_threads() was also added. This new service makes it easier to iterate over all the tasks/threads in a system and perform an action on them.
  • score/src/iterateoverthreads.c: New file.
  • ChangeLog?: Fixed screwup.
  • Property mode set to 100644
