Change History (most recent first):
|
|
|
|
<2> 8/26/93 IH #1108969 <KON>: Add modeDisplayManagerAware to size bits.
|
|
<30> 7/31/91 JL Updated Copyright.
|
|
<29> 6/14/91 JL Checked in official MPW 3.2Ä version. Put comments inside the
|
|
enum declarations to match DSG Database.
|
|
<28> 2/1/91 DFH stb,WS#DFH-910131c:Moved Process Mgr defined AppleEvent codes to
|
|
AppleEvents.h under new names. Put old names in
|
|
AppleEventsInternal.h since we don't want to break any compiles
|
|
at this point.
|
|
<27> 1/30/91 JL Checked in database generated file from DSG.
|
|
<26> 1/25/91 stb JDR: change processSignature to OSType from unsigned long
|
|
<25> 1/16/91 JDR (dba) Moved the Process Mgr error numbers into the Errors
|
|
interface file.
|
|
<24> 1/2/91 DFH Made sure routine parameter names match the Inside Mac Process
|
|
Mgr chapter documentation.
|
|
<22> 11/28/90 JL Put formal parameter names back.
|
|
<21> 11/19/90 DFH Comment changes.
|
|
<20> 11/7/90 JL Changed all #defines to anonymous enums
|
|
<19> 11/4/90 dba add some const stuff for input-only parameters
|
|
<18> 10/21/90 gbm (with dba) Made compatible with 3.2 C compiler (and incompatible
|
|
with previous compilers).
|
|
<17> 10/19/90 DFH Fixed LaunchApplication glue. Was an inline that popped
|
|
parameter, which is not C convention. Now uses #pragma
|
|
parameter and inline is plain trap number.
|
|
<16> 10/9/90 JAL CPlusPlus compatability.
|
|
<15> 9/4/90 JT Added modeUseTextEditServices to the list of process state
|
|
flags.
|
|
<14> 8/28/90 DFH Correct capitalization of highLongOfPSN and lowLongOfPSN
|
|
<13> 7/19/90 DFH Removed launchIsAutomatic and modeAutomatic.
|
|
<12> 7/16/90 DFH Launch, GetProcessInformation, and LaunchDeskAccessory now use
|
|
FSSpec instead of name/vfrefnum/dirid.
|
|
<11> 4/16/90 DFH Added AppleEvent definitions. Changed Launch params to use
|
|
unsigned fields, and made the constant for extended length
|
|
be the actual value rather than a bias.
|
|
<10> 3/21/90 DFH Renamed new mode flags to more closely match the SIZE flags.
|
|
<9> 3/20/90 DFH Added modeHLEventCompatible, modeNetHLEventCompatible, and
|
|
modeStationeryAware. Removed AppleEventMessage field from
|
|
AppParameters. No longer includes AppleEvents.h.
|
|
<8> 3/12/90 DFH Added AppParameters structure for launchAppParameters.
|
|
<6> 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> 2/3/90 DFH Added GetFrontProcess glue. Renamed launch flags and process mode flags to match ERS.
