Change History (most recent first):
|
|
|
|
<13> 8/26/92 DTY Roll in latest changes for A/UX.
|
|
<12> 1/22/92 DTY Take the synFOND field out of the synthetic strike table
|
|
structure. WeÕre gauranteeing unique font IDs, so this extra
|
|
differentiation wonÕt be necessary.
|
|
<11> 11/15/91 DTY Added synFOND to the SynEntry structure. (We might need to
|
|
store this information elsewhere if it turns out that developers
|
|
are looking at the synthetic fonts.
|
|
<10> 9/16/91 DFH Added GetCPUStatusRegister and SR definitions.
|
|
<9> 4/1/91 DFH (with John Iarocci) Merge in latest AUX support code. NOTE: No
|
|
AUX support code is referenced unless the build defines the
|
|
HAS_AUX_PROCESSMGR condition.
|
|
<8> 3/1/91 DFH KST,WS#DFH-910301a: Added xfiScriptCodeMask.
|
|
<7> 1/21/91 DFH (KSM) Removed system menu IDs, since they are now in
|
|
MenuMgrPriv.a.
|
|
<6> 1/15/91 DFH (VL) Conditionalize out the AUX call macros.
|
|
<4> 12/10/90 DFH Moved file attribute and finder flag equates from
|
|
OSDispatchPrivate.h.
|
|
<3> 12/5/90 DFH Added #defines for prettier calls to AuxDispatch. Removed
|
|
NewFXInfo since FXInfo is now in Files.h.
|
|
<0> 10/25/86 PYG New Today.
