Contains: Structures and externs of Process Manager global data
Written by: Erich Ringewald
Copyright: © 1986-1992 by Apple Computer, Inc., all rights reserved.
Change History (most recent first):
<45> 12/4/92 DRF Added nativeFPR storage area in PCB. Fixed up some #includes.
<44> 11/25/92 DRF Added additional PCB field for tracking the applicationÕs code
fragment manager context. Changes for <44> and <43> are
conditionalized under PsychicTV.
<43> 11/25/92 DRF Added some #includes for PowerPC Code Fragment Manager.
<42> 8/26/92 DTY Change ModSquadÕs funky conditional to use #ifdefs like everyone
else.
<41> 8/26/92 DTY Roll in latest changes for A/UX.
<40> 8/17/92 hjcr Adding support for OCE's "defer drag" feature. Conditionally
compiled under MODSQUAD
<39> 8/4/92 KST Added comments for the TSM change.
<38> 6/22/92 DTY #1033275 <csd>: Change the 16-1 to a 15 because of some compiler
idiosyncracies.
<37> 6/12/92 pvh #1032359: Added QUAD_ALIGN and QUADALIGN_MASK macros for 16 byte
alignment on '040 Macs.
<36> 3/30/92 DTY #1025416,<DDG>: Add skiaExists global.
<35> 3/25/92 DTY #1024114,<pvh>: Add c_PEntryFromProcessSerialNumber to the
OSDispatch table. Check out the comment in OSDispatch.c, version
12 about why this routine is being added.
<34> 2/18/92 DTY #1021226: Switch emMessageManagerGlobals again.
<33> 1/11/92 YK Two more calls and two more gloabls for TSM. NewTSMLayerOwner to
get the event for the floating window. RouteEventToSWM to do the
bottom line input.
<32> 11/22/91 DTY Add a semaphore, allocateGMBlkInSysHeap, which tells GMBlk to
automatically go to the System heap for memory instead of
mucking about with Process Manager memory first. This is a 7-Up
fix to prevent fragmentation of the Process Manager heap when an
'obit' event is sent.
<31> 10/16/91 YK Added InlineAware dispatch entry.
<30> 10/15/91 YK Added global data and dispatch entries for supporting the Text
Service Manager.
<29> 10/9/91 YK Added IMLayer(LayerPtr :global), NewFloatLayer and
DisposeFloatLayer (traps) all for supporting input windows for
text services. Particularly, FEP's (input methods).
<28> 10/4/91 JSM Change PsychoticFarmerOrLater to TheFuture.
<27> 9/22/91 DTY Change PsychoticFarmerAndLater to PsychoticFarmerOrLater.
<26> 9/16/91 DFH Removed INITSR (#define to 0x2000). Added initialProcessSR.
Needed for NuKernel.
<25> 9/13/91 DTY Conditionalise previous change so it doesnÕt get built for
CubeE. (ItÕll get built for PsychoticFarmerAndLater.)
<24> 6/4/91 DFH Added emMessageManagerGlobals to PCB.
<23> 3/22/91 DFH jmp,WS#DFH-910322a: Fixed FPUUserRegs defintion to use
"extended96" for type of FP registers. Was using plain
"extended", which is only 80 bits (SANE-style) rather than 96
bits (Motorola-style). This caused ReadWriteProcessFPURegs to
return less than the full complement of registers. This doesn't
effect any other code.
<22> 2/25/91 DFH DC,WS#DFH-910225a: Added p_scrapIsNotFromLaunch.
<21> 2/21/91 DFH dba,#82504, #82681, #83168, #83182, #83207: HiNewHandle rolled
into ProcessMgrHiNewHandle. Changed prototype. Added
SysZoneFloatSizes.
<20> 2/9/91 JWM DFH,#79583:Restart and Shutdown don't work in low memory
conditions. A new routine was defined -- GMBlk. It is modeled
after ProcessMgrHiNewHandle but checks the system heap if
ProcessMgrHiNewHandle returns a null handle.
<19> 1/28/91 DFH JSM,#81425: Removed inhibit_DAs global and PopUpMenuSelect
patch.
<18> 1/21/91 DFH (KSM) Process Menu is now called Application Menu.
<17> 1/15/91 DFH (VL) Conditionalize out the AUX fields in PEntry.
<16> 1/14/91 DFH (dba) Make system mode per process.
<15> 1/14/91 DFH (JDR) Conditionalize out AUX support.
<14> 1/10/91 DFH (JDR) Added p_preventFirstSysBeepPatch.
<13> 1/8/91 DFH (rdd) Got rid of pErrantProcess since it is no longer needed.
<12> 12/20/90 DFH (dba) Removed obsolete dispatch TWKill. Replaced it with
GetNextHighLevelEvent.
<11> 12/18/90 DFH Added GetScrap patch.
<10> 12/17/90 DFH Touched up Aliases.h include.
<9> 12/14/90 DFH Added kernelMode.
<8> 12/10/90 DFH Moved process icon info from PCB to PEntry.
<7> 12/5/90 DFH Added AUXIsPresent and AUX fields in PEntry. Moved VBLDesc and
DCEDesc here from SysMisc.h.
<6> 11/26/90 DFH Removed trespass() macro.
<5> 11/6/90 DFH Renamed emAppleEventsGlobal to emAppleEvents.
<4> 11/5/90 DFH Correct names for TEMPTOPMEM and TEMPDISPOSEHANDLE.
<3> 11/1/90 DFH Added prototype for DebuggerMsg().
<0> 9/2/86 ELR New Today.
