* HISTORY
* $Log: sched_prim.h,v $
* 19-Apr-90 Gregg Kellogg (gk) at NeXT
* NeXT: Declared thread_wait_result() proecedure.
*
* Revision 2.9 89/10/11 14:25:14 dlb
* thread_switch --> thread_run.
* [89/09/01 17:41:25 dlb]
*
* Revision 2.8 89/10/03 19:26:08 rpd
* Defined thread_wakeup, thread_wakeup_with_result, and
* thread_wakeup_one using thread_wakeup_prim.
* [89/09/01 01:30:53 rpd]
*
* Revision 2.7 89/03/09 20:15:35 rpd
* More cleanup.
*
* Revision 2.6 89/02/26 16:18:04 mrt
* changed #ifdef SCHED_PRIM_H_ to #ifndef
*
* Revision 2.5 89/02/25 18:08:14 gm0w
* Kernel code cleanup.
* Put entire file under #indef KERNEL.
* [89/02/15 mrt]
*
* Revision 2.4 89/02/07 01:04:15 mwyoung
* Relocated from sys/sched_prim.h
*
* Revision 2.3 88/07/17 18:57:09 mwyoung
* Added thread_wakeup_with_result routine; thread_wakeup
* is a special case.
*
* 16-May-88 Michael Young (mwyoung) at Carnegie-Mellon University
* Added thread_wakeup_with_result routine; thread_wakeup
* is a special case.
*
* 16-Apr-88 Michael Young (mwyoung) at Carnegie-Mellon University
* Added THREAD_RESTART wait result value.
*
* 29-Feb-88 David Black (dlb) at Carnegie-Mellon University
* thread_setrun is now a real routine.
*
* 13-Oct-87 David Golub (dbg) at Carnegie-Mellon University
* Moved thread_will_wait and thread_go to sched_prim_macros.h,
* to avoid including thread.h everywhere.
*
* 5-Oct-87 David Golub (dbg) at Carnegie-Mellon University
* Created. Moved thread_will_wait and thread_go here from
* mach_ipc.
