Comment (by johill):

 PPS: In thread.h and iterateoverthreads.c one could create some code like
 this. A possible implementation.

 /**  This defines the type for a method which operates on a single thread.
  */
 typedef void (*rtems_per_thread_routine)( Thread_Control * );
 typedef void (*rtems_per_task_function)( Thread_Control *,
                                             void * const pUserPrivate );

 /**
  *  This routine iterates over all threads regardless of API and
  *  invokes the specified routine.
  */
 void rtems_iterate_over_all_threads(
   rtems_per_thread_routine routine
 );

 void rtems_thread_per_each_callback(rtems_per_task_function pFunction,
                                 void * const pUserPrivate );



 void rtems_thread_per_each_callback(rtems_per_task_function pFunction,
                                 void * const pUserPrivate )
 {
   uint32_t             i;
   uint32_t             api_index;
   Thread_Control      *the_thread;
   Objects_Information *information;

   if ( !pFunction )
     return;

   for ( api_index = 1 ; api_index <= OBJECTS_APIS_LAST ; api_index++ ) {
     if ( !_Objects_Information_table[ api_index ] )
       continue;

     information = _Objects_Information_table[ api_index ][ 1 ];
     if ( !information )
       continue;

     for ( i=1 ; i <= information->maximum ; i++ ) {
       the_thread = (Thread_Control *)information->local_table[ i ];

       if ( !the_thread )
         continue;

       (*pFunction)(the_thread,pUserPrivate);
     }
   }

 }
