Change History (most recent first):
|
|
|
|
<33> 7/31/91 JL Updated Copyright.
|
|
<31+> 6/14/91 JL Checked in official MPW 3.2ƒ version. Moved Const and Type
|
|
reserved words to before the preceeding comment to match the
|
|
database. Moved "Process identifier." comment to after type
|
|
declaration to be consistent with C header.
|
|
<31> 2/1/91 DFH stb,WS#DFH-910131c:Renamed Process Mgr defined AppleEvent codes
|
|
and moved them to AppleEvents.p.
|
|
<30> 1/30/91 JL Checked in database generated file from DSG. (No change)
|
|
<29> 1/16/91 JDR (dba) Moved the Process Mgr error numbers into the Errors
|
|
interface file.
|
|
<28> 1/2/91 DFH Made sure routine parameter names match the Inside Mac Process
|
|
Mgr chapter documentation.
|
|
<27> 11/14/90 DFH Re-entered revision 25.
|
|
<26> 11/13/90 gbm Change <25> was garbled... I'm going back to the way it was in
|
|
<24> until Dave can figure out what went wrong...
|
|
<25> 11/13/90 DFH File param to LaunchDeskAccessory is now FSSpecPtr so that
|
|
caller can pass nil.
|
|
<24> 11/13/90 DFH Remove VAR from LaunchDeskAccessory. Correct casing for
|
|
launchParams.
|
|
<23> 9/25/90 DFH Fixed LaunchDeskAccessory param list.
|
|
<22> 9/4/90 JT Added modeUseTextEditServices to the list of process state
|
|
flags.
|
|
<21> 7/19/90 DFH Removed launchIsAutomatic and modeAutomatic.
|
|
<20> 7/18/90 DFH Uses FSSpecPtr (now that it exists) instead of ^FSSpec, in
|
|
ProcessInfoRec and LaunchParamBlockRec
|
|
<19> 7/16/90 RLC Fix LaunchDeskAccessory() interface. (per DFH)
|
|
<18> 7/16/90 DFH LaunchApplication, LaunchDeskAccessory, and
|
|
GetProcessInformation now use an FSSpecPtr instead of
|
|
name/vrefnum/dirid.
|
|
<17> 4/16/90 DFH Added AppleEvent definitions. Changed Launch param
|
|
constant for extended length to be the actual value
|
|
rather than a bias.
|
|
<16> 4/7/90 ngk Changed Size to LONGINT, since Memory.p is not auto-included.
|
|
<15> 3/21/90 HJR Fix Header.
|
|
<14> 3/21/90 DFH Renamed new process modes to more closely match SIZE flags
|
|
<13> 3/2/90 DFH Added modeHLEventCompatible, modeNetHLEventCompatible, and modeStationeryAware
|
|
<12> 3/20/90 ngk Remove AppleEvent dependency.
|
|
<10> 3/13/90 DFH Fixed LaunchParamBlockRec. launchControlFlags was missing
|
|
and launchFileFlags had the wrong type.
|
|
<9> 3/12/90 ngk Defined AppParameters.
|
|
<8> 3/12/90 DFH Added launchAppParameters field and AppParameters record.
|
|
<7> 2/8/90 DFH Copied projector revision comments to this file.
|
|
<5> 2/5/90 DFH Added modeXxx defs for SIZE flags portion of the processMode.
|
|
<4> 2/5/90 DFH Renamed and recapitalized to match the MultiFinder 7.0 ERS.
|
|
<2> 1/3/90 DFH Added GetFrontProcess glue. Renamed launch flags and process mode flags to match ERS.
|
|
** 1.2 12/07/1989 CCH Added LaunchApplication
|
|
** 1.1 12/01/1989 ngk Added new error codes
|
|
** 1.0 10/16/1989 ngk Initial submission
|
