@subheading CALLING SEQUENCE:
@ifset is-C
@findex rtems_iterate_over_all_threads
@example
typedef void (*rtems_per_thread_routine)(
Thread_Control *the_thread
);
void rtems_iterate_over_all_threads(

@subheading DIRECTIVE STATUS CODES: NONE
@subheading DESCRIPTION:
This directive iterates over all of the existant threads in the
system and invokes @code{routine} on each of them. The user should
be careful in accessing the contents of @code{the_thread}.
This routine is intended for use in diagnostic utilities and is
not intented for routine use in an operational system.
@subheading NOTES:
There is NO protection while this routine is called. Thus it is
possible that @code{the_thread} could be deleted while this is operating.
By not having protection, the user is free to invoke support routines
from the C Library which require semaphores for data structures.
