Raw Blame History

;
; File: TrapsPrivate.a
;
; Contains: Private System traps, not for public consumption.
;
; Written by: Jim Reekes
;
; Copyright: © 1992-1994 by Apple Computer, Inc., all rights reserved.
;
; Change History (most recent first):
;
; <SM10> 1/22/94 KW added some traps macros from the CygnusX1 ROM
; <SM9> 11/17/93 KW added a trap to turn on 040
; <SM8> 9/9/93 pdw Prettied and changed MakePageWriteThrough to nkMake… to be
; consistent.
; <SM7> 6/23/93 CSS Update from Reality:
; <3> 6/14/93 JDR Moved Get/SetTrapWordAddress into TrapsPrivate.a
; <2> 6/13/93 JDR Added _FigmentDispatch.
; <SM6> 6/6/93 BT Add _MFPrTypeStrings for process manager GetResource patch roll
; in.
; <SM5> 5/10/93 BT Add _HeapDispatch trap for Figment.
; <SM4> 5/6/93 SAM Added several new kernelVM dispatch selectors.
; <SM3> 3/11/93 SAM Added nkAllocateMemory to the list of Nanokernel macros.
; <SM2> 2/20/93 SAM Added all the private process manager traps. Added a slew of
; nanokernel traps and macros.
; <1> 7/22/92 JDR first checked in
;
;
; Notes: This file contains the traps allocated by the System, but
; are not for use by the public and therefore not for use
; by developers. At the time of this writting (the first
; check in) all of the private traps are scattered throughout
; the source files. The hope in creating this file is that
; all of these private traps will be collected into this file.
; If you add a new trap, keep this file in trap number order
; just like the public Traps.h. Also, it would be helpful
; if you add a comment about what the trap is used for.
;
; To Do: Add the traps and trap calling macros which are located in
; the following files
;
; {IntAIncludes}BTreeEqu.a
; {IntAIncludes}DispatchHelperPriv.a
; {IntAIncludes}fontPrivate.a
; {IntAIncludes}MenuMgrPriv.a
; {IntAIncludes}MFPrivate.a
; {IntAIncludes}PalettePriv.a
; {IntAIncludes}ScriptPriv.a
; {IntAIncludes}SCSIPriv.a

; Sound Manager traps
; SndAppDead is called by InitApplZone which vectors to jIAZInit, which then
; vectors to jSoundDead. This is done by the ROMs on Apple Sound Chip machines,
; for some reason that has been lost in history (probably due to the pre-MultiFinder
; assumptions). It is also called by CleanupApplication. So we've got them
; coming and going, but we really only want this trap to be called once a
; process is going away.
