Change History (most recent first):
|
|
|
|
<SM5> 8/5/93 JDR integrate component mgr from reality
|
|
<SM4> 7/21/93 RC House Cleaning from Reality
|
|
<6> 7/16/93 JDR Added SupportNativeComponents and kComponentIsNative.
|
|
<5> 6/13/93 JDR Rolled in the ComponentMgr sources from QuickTime 1.6.
|
|
<4> 11/12/92 JDR Created kComponentInitialTableEntries which was set to 32
|
|
entries in System 7.1, but I cut it back to only 16 to help save
|
|
some RAM for the general user.
|
|
<3> 12/12/91 DTY Get rid of the spaces in the file names
|
|
<2> 12/5/91 YK Rolled in QuickTime GM:
|
|
grow cmpnt table by smaller steps to preserve system heap
|
|
<8> 9/25/91 BAL Added an internal flag to mark cloned app-heap compononents as
|
|
subordinate to their sys heap parents.
|
|
<7> 5/18/91 dvb Thing->Component
|
|
<6> 5/2/91 BAL overlap rtDesc.FlagsMask and rtRefcon again.
|
|
<5> 4/1/91 MK make rtRefcon and rtFlagsMask separate again
|
|
<4> 3/28/91 BAL Do some file management. Added parentThing and Captured flag.
|
|
<3> 2/21/91 MK slime some globals for codec manager
|
|
<2> 2/16/91 BAL Added InitThingManager call.
|
|
<3> 12/30/90 bal changed name to thing manager
|
|
<2> 10/06/90 dvb Make it work
|
|
|
|
To Do:
